Grasscloth Engineering and Logistics – Technical Details Post

August 21, 2022
Grasscloth is a natural material that cannot be matched from strip to strip, so all the seams will be visible . In addition, there is usually a slight but noticeable color difference between strips / panels (called shading or paneling ) . So it’s important to plot the layout of the strips to give the most visually pleasing overall look. Usually this means balancing the width of strips so they are all equal , at least on the same wall . We call this engineering .
This wall presented particular challenges , due to the widths of the elements. Grasscloth comes 36″ wide . You can use your straightedge and a sharp razor blade and trim it down to any width you want.
The width of both the large wall spaces to the right and left of the bank of windows was 34.” The width of each window was about 35.” The width of the two spaces in between the windows was 7.”
So you’d think I could trim my panels on either side of the windows, and then over the windows, to about 34″-36″ – give or take a few inches (or fractions thereof).
But that would leave me with two 7″ wide strips between these 35″ panels. Although the look would be uniform and mirror-image from the center outward, moving from right to left you’d have: 35,” 35″, 7,” 35,” 7,” 35,” 35,” … those 7″ breaks were just not going to look right.
One option was to determine the width of the wall (189″) and make each strip an equal width. This worked out to six strips, each at 31.5″ Not good, because this would mean a seam down either far side. And since those sides were 34″ wide, that would mean a 31.5″ wide strip and a strip 2.5″ wide. Not attractive at all, and it would use up an extra strip of wallpaper.
This six strips @ 31.5″ wide scenario might also land with a seam smack in the middle of those 7″ wide interludes in between the windows. Not attractive at all.
So I decided to make the two outer strips 35″ wide. That left 119″ of wall space above the windows to be covered with wallpaper. Do some math and you get four panels of 29.75″ wide. This gave a balanced and uniform look to the area over the windows, and also prevented seams from landing between the windows.
Moving right to left, I cut and hung the full length outer strip first. Then I cut and hung the strip over the window on the right. Then I measured to find the centerpoint of the window in the middle. Turns out it was a bit less than 29.75″ away. So I trimmed that next over-window strip accordingly.
Once that was in place, I measured from that center point above the middle window out to where my left full-height panel would fall, 35″ out from the wall. Took the resulting measurement and divided by 2. Lo and behold, each of the next two panels over the window was going to be a bit wider than 30.” No problem. No one (but a paperhanger or maybe an engineer) is going to notice a 1/4″ or even a full 1″ difference in widths between this strips over the windows.
Another thing to point out … it’s important that I took measurements before cutting these strips for this second left-hand section. Because, since grasscloth comes at 36″ (and walls can be wonky), if my strips had been narrower (say, 28″), that last full-height panel on the left might have ended up needing to be 37″ wide – and that wouldn’t work because it only comes 36″ wide – plus you need at least 1/8″ to wrap around the corner.
Luckily I had the flexibility to be able to trim the panels over the windows to any width needed, to accommodate all this.
If you’ve followed all this so far, let me also toss in that we also need to figure how to get paper in between those windows. More on that below.
In this scenario, I’m moving from right to left.
Area beneath the windows needs to be treated in the same way, and preferably with widths that match what’s going on above the windows. In addition, it’s tricky because after you move across 12′ of wall space, the strips above and below the windows are going to twist and torque out of shape, so that last full-length panel on the far left might not butt up perfectly with the last strip under the windows.
The grasscloth is black , and my wallpaper primer is white . It’s common for teeny gaps to appear at the seams . In this case, it’s likely that white wall would peek out from those gaps. So I like to stripe under where the seams will fall with dark (diluted) paint . This takes measuring , plotting , and also a heat gun to get the paint to dry before the wallpaper hits it, to avoid staining. You can do a Search here to read more about this technique .
Now let’s talk about getting wallpaper in between those windows.
As you can see in the photo, if I hang a 30″ wide strip, a whole lot of paper is going to be cut off and thrown away. Also, a whole lot of sticky, pasted paper is going to bump against that window molding and maybe even the window glass. A lot to clean up! And unwieldy, to boot.
My solution was to stop the wallpaper just a little below the tops of the windows. Then I would patch in a 7″ wide strip in between the windows. This is trickier than it sounds, because, if it were a paper wallpaper, I could simply cut along a design motif and overlay the 7″ wide piece. But grasscloth is thick and overlaps don’t look good. Also grass has no design elements , and the reeds of grass don’t necessarily fall perfectly horizontal , and even if you cut everything perfectly true to square , if the window molding is a teeny bit off-plumb , then your edges won’t butt up perfectly.
So that’s a good reason for striping the black paint under where the butt join will occur.
Same thing for the sections under the windows. I measured and positioned the strips so that the top edge (which I had trimmed to be perfectly horizontal) fell between the narrowest part of the windowsill molding, for less visibility.
I admit, instead of butting the two pieces, here I did overlap the 7″ wide strip about 1/4″ onto the piece under the window, right at that narrow junction. It’s only about 3″ wide, and I figured no one is going to be examining it that closely, anyway. This saved me about a half an hour of measuring, trimming, testing, repeat, repeat.
This is my second window interlude, and by this time I had realized that it’s hard to trim stiff grasscloth around intricate moldings precisely . So I used paint to fill in the edges around the window molding, just in case there might be any gaps between the grasscloth and the molding, so you would see black instead of the white molding paint. I did this with a small sponge; if I had used an artist’s brush it would have been a bit neater and tighter to the conforms of the molding. But sometimes you’ve gotta relax and realize that no one’s going to be scrutinizing the insides of moldings below shin-level.
Area over windows finished, with drapes back in place.
Turns out this particular grasscloth is so uniform in color (quite unusual, I will add), that you can’t really see the panels , nor their equal widths , anyway. I’m still glad I took the time to do all this math and trimming.
Area below the windows, done. That last seam on the left bears some explanation, too. Moving across the top of the windows, I measured that that last strip – the full-length strip – would need to be exactly 35″ wide. It butted up nicely to the last strip above the windows.
But, due to twisting , shifting , expansion , unlevel and unplumb walls and ceilings , and other factors, there is a really good chance that that last 35″ wide strip would not butt up perfectly with the last 30″ wide strip under the window . So I planned to splice these last two strips together.
Yeah, the drapes are hanging there, I coulda overlapped the two strips about 1/2″ and the drapes would have covered it. With a thin wallpaper, I probably would have done this. But grasscloth is thick, and an overlap would be visible , and also the adhesive / paste can’t be trusted to adhere as well to grass as it would to paper .
So I plotted for a splice. Instead of trimming my last strip under the window to 30″ (read above), I trimmed it to 32″ wide. That way, when I hung the last full-length strip to the left, which was 35″ wide, it overlapped the piece under the window by a few inches. Then I did a double cut and spliced the two pieces. See below for details about that technique.
Grasscloth is 36″ wide, and this wall area is wider than that. So two strips were needed. This means you’re going to have a seam, and since grasscloth seams are always visible, it looks best to plot to have the seam fall down the center. It uses more wallpaper to do this, but it looks much better than having, for example, a 36″ wide strip next to an 8″ wide strip.
As mentioned above, in case you get thin gaps at the seams, a dark stripe of diluted craft paint under where the seam will fall, will prevent white wall from showing through.
Rounded / bull-nosed edges and corners have been popular in new construction for at least 10 years. I wish they’d go away. They’re very difficult to trim around, and hard for the paper to conform to and adhere to.
It’s very hard to trim around that rounded edge, because the paper is hanging over and blocking your view, because grasscloth is thick and stiff and your fingers can’t feel through it, and because the edges aren’t necessarily true and plumb so a laser level or other level won’t help you much.
I use this little gadget as a trim guide. It’s actually a small section of the same corner bead material that drywallers use when they assemble these walls. Cut to about 1″ long and notched in different places where you might trim along the edge of the wall.
It’s intended that you place your trimming knife in one of the notches and slide the gizmo along the edge and make your cut. I find that awkward and also inaccurate. So I prefer to use the notches as a guide and mark where I plan to trim with a pencil. Since this wallpaper is black, I used this marking pencil from my home sewing kit instead. Chalk might work, but I was afraid it might now wipe off completely.
The pink pencil line was barely visible, but it was enough for me to use a scissors to trim along the grasscloth. I like this better than using a razor blade as I can see better, and also less chance of scoring into the primer or wall. Which raises its own set of issues – do a search here to find previous posts.
Inside view of the trim guide.
Finished arch. Note the four panels of equal width above the arch. And two flanking full-height panels also the same widths.
I was lucky that there was no pattern to match, so I was able to butt my two flanking strips right up to the edge of the bull-nosed corner. No trimming needed! Then I measured the remaining width between these two strips (the area over the arch), divided by four, and cut four strips of equal widths.
I hung the two on the left, and then one on the far right. This left one strip still to be positioned to the right of center. So the pieces are going to meet over the arch, rather than the last strip falling in a corner.
Same as the last strip under the window (discussed above), it’s really difficult to get your last piece to fit in here perfectly. I’ve done it, but it takes a lot of measuring, trimming, testing, retrimming, and often starting all over again.
So I did a double-cut / splice.
A double cut involves cutting each strip an inch or so wider than it should be, and overlapping the two. Then you take a straight edge and sharp razor blade and cut through both layers. This handy tool is a wonderful non-slip guide for this process. It was invented by an installer colleague in the Wallcovering Installers Association ( WIA ) and she has them fabricated in various lengths (along with other cool tools ) and sells them on-line. Contact me if you’re interested.
Anyway, it takes a lot of strength to cut through two layers of grasscloth, so somewhat difficult for lil’ ol’ me.
You also want to be sure to not cut / score into the wall, because the tension of drying wallpaper can tug at the wall and cause it to actually come apart, leaving an open seam that’s difficult to repair.
So you’ve got to put some padding under the wall where the cut will take place. I use special strips of polystyrene (hard but flexible plastic) to pad the wall. Also invented by a colleague in the WIA , who also sells other cool tools and supplies. Contact me if you’re interested.
This black grasscloth was printed on a white substrate. If the seams aren’t absolutely tight, there can be worries about the backing showing through to the front. So sometimes we’ll take a piece of chalk or pastel (never oil pastel or permanent markers because they bleed and stain ) and run it along the edge of the paper – from the back, and taking care to not get chalk on the surface.
I do this frequently with dark papers ( do a search here to see previous posts ) but opted not to do it with this grasscloth. It wasn’t necessary, and might have stained the porous reeds of the grass. It was beneficial, though, to have striped dark paint on the wall under the seams, as mentioned above.
Ugh. Grasscloth comes 36″ wide, and this section of wall is 38″ wide. It’s not visually pleasing, nor is it easy from an installation point of view, to have a 36″ wide strip next to a 2″ wide strip. Or to use scraps and put a 25″ wide strip next to a 13″ wide strip.
So best to plan two strips of equal widths. Two strips, each 19″ wide, with the seam down the middle.
Actually, the strip on the left was 19″ wide, but I trimmed the strip on the right to 21″, because I like the wallpaper to extend 2″ over the top of the door molding. This provides a more stable surface in case of shifting foundation or walls, and less likelihood (knock on wood) of the seam opening up should the house / drywall experience shifting.
Note that design “rules” caution against seams down the middle of spaces. But it would have been more visually distracting (and used up more paper) to have made three strips of each 12.75″ wide. And would have looked even dumber to have used scraps left from other walls and put together two strips of disparate widths.
So the homeowner and I discussed during our initial consultation , and she was happy with the center seam. Once it was all finished, this particular grasscloth was so even in tone that you barely see the seams, anyway. Win-win!
This did use up additional paper, though, as noted in a previous photo above.

Saving Paper, Right and Left

August 16, 2022
Here I’m hanging wallpaper , moving from left to right. The wallpaper is 21″ wide . The width between my last strip on the right and the wall is 15″.
That means that I will have to cut off 6″ width of paper – which usually ends up on the trash pile. Here I am using a straightedge to cut that off.
Since that strip of wallpaper is 9′ long, we’re losing 4.5 square feet just in this one small area.
(Another reason to always buy a little extra wallpaper … you can’t use every square foot !)
Note that I’ve actually cut my strip to 15.5″, so I’ll have a little excess for trimming at that right wall.
Back to that 6″ (actually 5.5″) wide strip on the trash pile. I never throw anything away until the job is finished. Because I just might be able to use a piece somewhere. As in this case …
After the right side of the wall was finished, I started moving to the left. When I came to the left corner, my last strip needed to be 1.5″ wide.
Instead of cutting a whole new 9′ long strip off the roll of wallpaper, I reached for that scrap pile and pulled out that narrow 5.5″ piece that had been trimmed off the opposite edge of that strip on the other side of the wall.
This was the correct pattern match to meet up with the strip on the left side of the wall in the photo above.
Here I am trimming a 2″ strip (1.5″ + .5″ for trimming allowance) off the appropriate edge of that scrap piece. Note: Be certain you are trimming from the correct side of that scrap! Or the pattern won’t match and you’ll have to cut a fresh 9′ length after all. 😦
Here the wall is finished. For the two corners, only one strip was used, due to being able to cut both a right and a left piece out of only one strip of wallpaper.
Now I’m going to get into a little more technical stuff, that usually only a paper hanger will understand. The pattern above is what we call a straight match . This means every strip is the same. And that a particular design motif (like the pink flower) hits the top of the wall at the same position on every strip. My right-left trick above only worked because this was a straight pattern match.
But … you can make it work with a drop pattern match, too. A drop match means that every other strip is the same. On a drop match, the pink flower will be at the top of the wall on one strip, but drop down a few inches (half the length of the pattern repeat ) on the second strip. By the third strip, it will be back up at the top of the wall.
This also leads to using A and B strips. Confusing – but we wallpaper installers get it.
Anyway, my trick explained above works for straight matches, with all A strips. But if your right corner of the wall ends in an A strip, and the left corner needs a B strip, your scrap from the A strip won’t match the pattern repeat needed on the left side of the wall. So you’re gonna have to cut a whole new 9′ long strip, just to cover that 1.5″ gap at the left corner.
But – WAIT! – there is a trick to outsmart this. If you plan ahead, and count your strips, and plot the layout, and engineer your project, you can avoid needing that 9′ long strip.
When you’re cutting off from the bolt that last A strip for the right corner, just cut it a little longer. Cut it long enough to include the B pattern match. Do a little math and then do some visual checking to be sure you’ve got it right. Then cut your strip.
When you get to trimming off the 15.5″ wide right edge, it will be a few inches longer than the previous strips. So you’ll throw away a tiny bit more when you trim at the bottom of the wall than if it were a straight match.
Correspondingly, the 5.5″ wide scrap left over, from which you will cut the 2″ wide strip needed for the left corner, will be a few inches longer at the top of the wall than needed.
So by juggling the A & B pattern match / repeat , you’ve saved a whole 9′ long strip. This is good, because you always want a bit left over, in case of need for repairs down the road.
This fun pattern is by Missoni Home , which is made by York . It’s a textured embossed vinyl on a non-woven , paste the wall backing and was a very good paper.

Thin Blue Plastic Tape Keeps Paste Off The Wall

August 7, 2022
Panel of wallpaper lying on my pasting table. The left edge will go up against a painted wall that is not to be wallpapered. It’s important to keep paste off this wall, because the paste can cause the paint to crackle and flake off. Yes, you can wipe paste off the wall, especially if it’s a gloss paint. But better to not get paste on the wall in the first place.
So I’ve placed a strip of this cool blue plastic tape along the edge. It sticks to the pasted wallpaper, but will not let paste get onto the wall.
Here is the wallpaper in place, with the little 1″ overage wrapping onto the wall to the left. See how the blue tape is preventing paste from getting onto the wall?
Once I finish trimming, I will remove both the excess paper and the blue tape. Be sure to remove any blue tape that is still behind the wallpaper.
This also works for ceilings and for abutting another strip of wallpaper.
This tape is much better than painter’s plastic or ” caution tape ” because it is lightly tinted so you can see it, it’s translucent so you can see through it, it has the perfect body – thicker than painter’s plastic but more flexible than caution tape, and has a unique textured surface that makes it handle nicely, plus you can easily snap it apart so there is no need for scissors or razor blades.
It’s made in Japan and tricky to get. If you’re interested, email me at wallpaperlady@att.net and I’ll hook you up with the supplier.
The very edgy wallpaper? It’s by Spoonflower and called Serpents and Apples .

Sneaky Snaky Dining Room Accent Wall

August 6, 2022
Beautiful symmetry …
But look closer – those intertwining lines aren’t fronds of vegetation – they’re snakes !
The wall before. It’s a mid-century home, but the drywall here is new. Per my request, the contractor left it taped and floated , but not painted or covered with any coating .
I had planned to simply prime this wall. But after examining it more closely, the surface was a little grittier than I like. So I ended up applying a very light skim-coat and sanding it smooth .
Here the smoothed wall has been primed with Roman Pro 977 Ultra Prime .
I’m plotted out the center of the wall and am using my laser level to ensure that the design in my first strip falls right along the center, and also is nice and plumb .
My work table with two strips of wallpaper . Spoonflower packages its wallpaper differently from other companies. It comes in widths of 24″ and lengths of your choice of 3,’ 6,’ 9,’ or 12.’
Get their Pre-Pasted Removable Smooth option, which is water-activated , and is wonderful stuff.
Do NOT get the Peel & Stick , nor the Traditional Pebble . The P&S and the Traditional are both very difficult to work with, and can lead to bubbles and creases on your walls , plus cause damage when the wallpaper is stripped off later.
Back to the photo – the blue cube thing in front is my laser level , shooting its red line at the wall.
Close-up
I’m using this blue plastic tape on the edge of this strip of wallpaper. This will prevent paste from getting onto the wall or ceiling.
The accent wall stops in this left hand corner, so I need to trim off the excess. But I don’t want to get paste onto the un-papered wall. Paste can cause the wall paint to crackle and flake off.
So here you see how the blue tape is keeping paste off the wall. Once I finish trimming, I’ll check the back to make sure all of the blue tape has been removed. Any areas where the blue tape might be still on the back of the wallpaper , the paper won’t adhere to the wall .
This tape is available to paperhangers / installers . If you’re interested, shoot me an email wallpaperlady@att.net
Another thing about Spoonflower , the seams are meant to be overlapped, by 3/4″ . Note that this does create a ridge that runs vertically the length of each seam. In the grand scheme of things, this isn’t very noticeable.
Actually, there are advantages to overlapping seams in this manner. No worries about white substrates showing at the seams, nor the paper shrinking and leaving gaps at the seams.
Also, in case of unstable walls that might come apart ( delaminate ) under the tension of the drying / shrinking wallpaper, overlapping disperses the tension and helps prevent wall failure.
This pattern is called Serpents and Apples and is by Spoonflower . Spoonflower has a lot of cute designs , and also a good number of fun avant garde patterns like this one.
The homeowners have some other non-typical décor that will meld perfectly with this wallpaper. Think life-sized skeletons .
… Notice how that light fixture hanging in the center of the wall kinda looks like a skull ? …
The home is in the Oak Forest area of northwest Houston .

Inexplicable Pattern Match

July 17, 2022
This happens not infrequently, and it’s puzzling to me. At the top of the wall, the pattern match drops down to the right.
Yet at the center of the wall it matches perfectly.
But get to the bottom of the wall and it drops again, but this time to the left.

Yes, some papers do stretch / expand when they get wet with paste. But that’s not the situation here, because this is A.) a non-woven material, which generally do not expand, and B.) every strip was treated the same way. In other words, if every strip is pasted, booked, and left to sit for the same length of time, ALL the strips should expand the same amount, right? And the pattern should match at the top, middle, and bottom. Right?

But even that argument doesn’t apply, because this, again, is a NW / non-expansion material, and, besides, I didn’t paste the wallpaper but pasted the wall instead. So the material had no chance to get wet or swollen with paste.

I believe this is a factory trimming issue. Somewhere along the line, the trimmers got off-track, or started trimming on the bias, just enough to throw off the pattern match.

In cases like this, the rule of thumb industry standard is to match the pattern as best as possible at eye level (middle of the wall) and let nature take its course, as they say, on the upper and lower sections.

Luckily this particular pattern only had one motif area that matched across the seams, and there were only three of those per the height of each strip. So the two slight mis-matches were both way above and below eye level, so not very noticeable.

This pattern is called Palm Leaves and is by Cole & Son . Other than this printing snafu, it’s a good quality wallpaper. See previous post

No Vanity or Toilet Tank Makes for Easier Hanging

July 7, 2022
The husband removed the powder room’s vanity , and also the tank on the back of the toilet. This made it immensely easier for me to hang the wallpaper. The toughest part of today was trimming around those three pipes, which really wasn’t too hard at all.
Having a blank wall also means that the wallpaper can run all the way down to the floor, rather than having to be cut along the top of the vanity. This is really nice, because it eliminates the worry of water that splashes onto the wall or backsplash getting wicked up into the wallpaper – which can cause the seams to pull away from the wall.

Don’t Assume the Width

June 30, 2022
Here’s a finished map / mural on an accent wall in a child’s room in the Tanglewood neighborhood of Houston.
It’s made by Rebel Walls ( rebelwalls.com ), one of my favorite mural companies, and was custom-sized to fit this wall.
The mural came in a set of nine panels. The instructions above explain how the mural should be hung.
Careful measurements are important, both before ordering (note: Always let the wallpaper installer calculate rollage and mural dimensions before your order ) and then before you start hanging the mural.
This one large roll was cut apart into nine panels. You see them rolled up at the top of the photo.
Each of those panels was 19.75″ wide. So based on that, you might start measuring and calculating and plotting where to position your panels on the wall.
STOP!
Just because the manufacturer’s stock comes 19.75″ wide doesn’t mean that the printed part of each panel fills that full width.
The mural was custom-sized to fit the wall, right? The width of the wall is not an exact multiple of 19.75″. That means that the printed portion of the last panel will be narrower than the others. As you can see in the last photo, that narrow portion turned out to be just 2.5″ wide.
So it’s important that you unroll every strip / panel and take careful measurements of both the wall and the wallpaper , before cutting anything and definitely before pasting anything to the wall.
One more thing, while we’re on the topic of murals. Please don’t order until the paperhanger has measured and figured . It’s very important that the mural NOT be printed to the exact dimensions of the wall. FOUR INCHES of ” bleed ” are necessary to be added to EACH DIMENSION (meaning, four inches added to both width and height ). This will allow for trimming at floor and ceiling , and will accommodate walls / ceilings / floors that are not perfectly level or plumb.

My Work Set-Up

June 25, 2022




Here’s my pasting / trimming table , set up in my client’s living room, which is just a few steps away from the hall bathroom where I’m hanging wallpaper. In that room, of course, I have my ladder, as well as my smaller hand tools used for actually getting the paper onto the wall.

More William Morris Strawberry Thief in Houston Heights Hall Bathroom

June 24, 2022
Because I feared unstable walls in this 1920’s bungalow in this neighborhood (do a Search for previous posts), before hanging the decorative wallpaper, first I hung a non-woven liner paper on all the walls. That’s the white material you see in the photo.
The liner was hung horizontally so its seams can’t line up with the decorative paper. The idea is to disperse tension from drying wallpaper and changes due to humidity and etc., so as to deflect tension away from sketchy wall surfaces, and thus prevent delamination of multiple unstable layers deep inside the wall. Again, do a Search here to learn more.
Finished vanity area, with pattern centered on the light fixture.
Corner shot.
This colorful and symmetrical pattern is quite popular; I’ve hung it a number of times just this year.
Englishman William Morris designed wallpaper and fabrics during the late 1800’s and early 1900’s.
The styles then were Art Nouveau and Arts & Crafts. This design reflects a bit of each.
Wallpaper expands when it gets wet with paste, and then can shrink just a tad as it dries. The liner helps prevent that, but you can still end up with teeny gaps at some seams.
To prevent the white backing from showing through, I run a stripe of dark paint under where each seam will fall.
I use matt finish craft paint from the hobby store, diluted with a little water (in the orange bottle cap) and smeared on the wall with a scrap of sponge. Use a ruler or level and a pencil to mark where you want to stripe the dark paint.
Remember to allow for that expansion as the paper absorbs moisture from the paste. Meaning, if the paper is 20.5″ wide, and expands 1/2″, you’ll want to run your line at about 21.” And make sure that your painted swath is about an inch wide.
I also run a bit of dark chalk along the edges of each strip, to prevent the white substrate from showing at the seams (no photo).
Morris & Co. makes this iconic Strawberry Thief.
Interestingly enough, most times when I’ve hung a Morris paper, it’s been a non-woven paste-the-wall material.
Today’s option was a surprise – a traditional British pulp . This is a pretty basic and somewhat old-fashioned type of substrate . Sort of like construction paper, or the pages of an old family Bible .
The paper is very fragile , and can tear easily. You have to keep using new razor / trimming blades, because the material dulls blades quickly, and when dull they will drag and tear the paper.
Pulp papers also require a soaking / booking time after pasting , to allow time for the material to absorb the paste , soften a bit, and expand . The edges of the strips like to dry out , so I’ve learned to dip about 1/4″ of the booked ends ( booked means the pasted side of the wallpaper strip is folded onto itself, bottom edge folded up and top edge folded down to meet in the middle), into a bucket of clean water.
Then it goes into a black plastic trash bag to soak and relax for a few minutes before hanging. I use this opportunity to paste the next strip.
Non-woven wallpapers have advantages, because they do not expand when wet, and therefor you can get accurate measurements. They also can be pasted and hung immediately, with no waiting time. Alternately, you can paste the wall .

Logistics for Hanging Jungle Wallpaper Mural in Nursery

May 19, 2022

Let’s do some engineering so we can get this mural on the wall. The wall is a few inches less than 12′ wide, and 9′ high.
The mural comes as a set of four panels, and the total width of the mural is 6′ wide x 9′ high.
Therefore we need two 4-panel sets to span this wall.
Here is the first set of four panels, pasted and hung. A really tricky thing with murals is that the strips / panels you place next to your first set need to match up with the existing pattern. Meaning, the panels need to be able to be hung consecutively next to each other and have the pattern continue uninterrupted.
Not all murals are designed to continue from one to the next. Some will only fit a wall of certain dimensions.
Still others are custom made to fit specific sizes … but that’s a topic for another blog post.
You’re looking at two sets of mock-ups of the mural, side-by-side. The dotted lines show each individual panel.
Toward the center, you see where Panel 4 of the mural on the right meets up with Panel 1 of the mural placed on the right. You can see that the trees and other elements from the mural on the left match up with the motifs on the mural to the right. This is good! It means that we can place murals next to each other to cover a wider wall space.

Here is the finished wall with two murals placed next to each other, with the trees and animals continuing from one mural to the next.
Second issue: The wall height between crown molding and baseboard was exactly 9′ high. The mural came exactly 9′ high. This might sound perfect – but it ain’t agonna work.
The wallpaper / mural needs to be a few inches (preferably 3″-4″) taller than the wall itself. (Same goes for width) This little bit of wiggle room allows you to trim at the top and bottom of the wall. And it allows for walls that are not perfectly plumb and floors and ceilings that are not perfectly level.
In this case, it wasn’t going to be possible to get the mural to fit inside that 9′ high space across a 12′ wide wall without going off-track a bit. We needed about 2″ of extra height at BOTH top and bottom.
Well, you can’t make the wallpaper mural any taller, so we opted to make the wall shorter. The builder added an extra tall baseboard along the bottom of just this one wall.
This reduced the wall height by about 3″, which gave us just enough extra paper length to split between the ceiling and baseboard. A little will be trimmed off at the ceiling line, and a little off the bottom / baseboard.
If you look at the picture of the finished wall, the 4th photo, you’ll see that there are more “important” design elements at the bottom of the mural than at the top. The manufacturer does this on purpose, because they know that some of the mural will need to be cut off, in order to accommodate different wall heights, and for trimming at the ceiling and baseboard. Nearly a foot can be trimmed off the top of this mural without losing anything like an animal or a tree top.
The same is not true about the bottom, though. As you can see in this photo, the designer has let elements run all the way down to the bottom of the mural … leaves, plant stems, and, as in the photo above, a bird’s feet.
I tried to raise the strips up as high as possible, to avoid cutting off his feet. But I had to leave enough to accommodate trimming and wonky walls. So, as you see in the photo, the poor guy got his feet cut off.
Still, all this is happening at the bottom of the wall, and no one is really paying attention to this area. Plus, there will be furniture in front.
Still, all worth noting.

Some take-aways from this post that I hope you will keep in mind …
~Never order a mural to the exact dimensions of the wall. Add 4″ to height & width
~Consult with the paperhanger before ordering any material
~Rather than a mural that comes in one set size as this one does, consider a custom-sized mural that can be made to fit your specific wall. I like rebelwalls.com among others.
