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.

Palm Leaf Accent Wall

July 16, 2022
Finished living room accent wall. This was a looong wall – 24′ wide. It took 14 strips of wallpaper!
Before. I’m getting ready to skim-float the textured wall to smooth it, then apply a wallpaper primer .
Ready to hang, with my “A” and “B” strips lined up in the order they will be hung.
This is a paste-the-wall product, and I like to roll them backwards so the surface doesn’t bop into the paste as I position the strips on the wall. I secure with elastic head bands from the dollar store.
First strip starts in the center of the wall, both to balance the pattern. But also because the ceiling line is way not level and the pattern will go off-track at the ceiling, this will minimize the tracking by spreading it outward 12′ each way from the center. If I start at one corner, the tracking would be a lot more noticeable by the time it crossed the whole 24′ of wall.
Close up.
This is simply called Palm Leaves and is by Cole & Son , a good brand. It’s a non-woven material and is designed to strip off the wall easily and with minimal damage when you redecorate. It’s also a little more durable and stain-resistant than paper wallpapers. It was very nice to work with.
The home is in the Westbury area of Houston.
The couple has mid-century modern furnishings, and this wall looks fantastic as a backdrop !

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.

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 .

Bright Colorful Wildness On Bedroom Accent Wall

May 29, 2022
Textured wall has been skim-floated, sanded smooth, primed, and ready for wallpaper.
Done!
Here’s how we got there …. First, this is a non-woven , paste-the-wall material. It’s nice paper, but very stiff and wants to remain curled up. So to get it to cooperate, after cutting my strips, I roll them backward, backing side facing out, and secure with an elastic hairband.
This helps get rid of the curl, and also ensures that when I’m on my ladder at the wall and unroll the strip, the face will not bump into the pasted wall.
After finding the mid point of the wall, and the center of the wallpaper pattern (beware – it’s usually not perfectly in the center or at the edge of the paper), I draw a plumb line (or use my laser level) and hang the first strip against it.
It’s important to start in the middle, first to get the pattern centered.
Next, because ceiling lines are never perfectly level, the pattern can start to go off-track as it moves across the wall. Meaning, the motif I placed at the tip of the wall may start drifting up or down.
By starting in the middle and working outward, any drifting is lessened because it’s split between the right and left sides of the wall.
Close up.

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.
Jungle Wallpaper Mural is by Lulu and Georgia and is in the Sure Strip line made by York .
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.

Making A Corner Look Straight When It’s Not

March 25, 2022
Here I’m hanging wallpaper from right to left, working around this corner. I’ve wrapped the paper 1/8″ around the corner, and then cut a new piece that will overlap that 1/8″ and continue to move to the left. (Search here to learn more about turning inside corners.)
This is a 100 year old house, and this corner is way off-plumb – on both the right side and the left side. The chair rail, however, is perfectly level.
Here, the pattern matches nicely at the bottom of the wall. But as it moves up, the crooked corner takes over, and the pattern becomes mis-aligned.
By hanging the paper crooked, I can match the wallpaper pattern perfectly in the corner. But that will skew the left edge of this new strip off-plumb by slanting it to the right. That means that every subsequent strip will track off-plumb … and the motif at the top of the chair rail will start to climb uphill.
Since the chair rail is so prominently visible, I think it’s more important for the pattern motif to be straight along the chair rail, than to be perfectly matched in the corner.
But I didn’t like the way the pattern was getting un-matched at the upper part of the wall. I thought I could make it look better.
This design gave me something to fiddle with.
One option was to cut the paper vertically between the two rows of “swoops.” Then I could match the pattern in the corner, and pull the excess paper to the left, overlapping one strip on top of the other about 1/4″ at the top and tapering down to nothing at the chair rail. It’s a thin paper in a room with not-great lighting, so this overlapped lip would not be very noticeable. Still, I thought I could make it look better.
I could make the overlap invisible by trimming the paper along the design. Here I’ve removed that corner piece.
On the left is the strip I’ve cut off.
Here I’m putting the strip into place, and making sure that the pattern matches nicely in the corner. This pushes the upper part of this cut strip further to the left, so it overlaps the other strip of paper just a little
Now, instead of a visible straight overlap the full height of the strip, the overlap comes along the rounded edges of the design. That black line disguises the overlap beautifully!
Here it is nicely matched in the corner, with invisible overlap along the curved black line.
The excess still needs to be trimmed off at the ceiling and chair rail.
Mission accomplished! The design matches nicely in the corner, the paper moving to the left is hung perfectly plumb, and the motifs are all at their proper heights along the chair rail and ceiling.

Preventing White From Showing At The Seams

March 10, 2022
When wallpaper gets wet with paste, it expands a bit. And when it dries, it can shrink just a tad. That teeny gap at the seams can expose the wall underneath it. This can happen even with the non-woven materials, which are supposed to be dimensionally stable.
In addition, manufacturers usually print on a white substrate, so sometimes you see the edges of the paper at the seams, too.
All this is much more noticeable on a dark paper, such as here.
One thing I do to prevent / minimize this is to strip the wall with dark paint under where the seams will fall. So even if a seam opens up a bit, you’ll see dark, not white.
Since non-woven wallpapers don’t expand (much), it’s easy to measure the width of your strips and plot where the seams will fall, use a level, and then apply the paint.
I use plain old craft paint from the hobby store. I use a scrap of sponge and dip that in water (in my orange bottle cap) then into the paint, and then run my stripe down the plumb line I’ve drawn on the wall or used my laser level to shoot a vertical line.
It’s important to not get the paint too heavy or thick, because the wallpaper paste may not want to grab ahold of paint like it wants to hold on to a wallpaper primer. And definitely don’t use a gloss paint.
Be sure that it’s good and dry before you hang the wallpaper. A heat gun will speed things along if needed.
Not pictured, but you can look up other posts here … I also take a bit of chalk of a corresponding color and run it along the edge of the wallpaper to cover up that white edge. It’s important to apply the chalk from the back, to avoid getting any on the front of the wallpaper. Some colleagues use water markers, pencils, or gouache paint. Whatever you use, do not use anything with oil-based inks or colors. These will bleed and stain your wallpaper.
Chalking the edges is more important than striping the wall, IMO.
This pattern is called Allure and is by Graham & Brown , a brand I like a lot.

Paint Stripes to Prevent White Wall Peeking Out

January 8, 2022
Sometimes (usually) wallpaper expands when it gets wet with paste and then shrinks just a tad when it dries. This can result in hair-breadth gaps at the seams. Usually not a big deal. But when the paper is dark and the sub-surface is light, you can end up with white wall visible at the seams.
So sometimes I’ll paint a stripe of matching color behind where the seams will lie. Measure to plot where the seam will fall, then use a level and pencil, or a laser level, to indicate where, and then run a stripe of paint along that line. Make the stripe wide enough to accommodate slight variations in measurements and wallpaper expansion.
I use craft paint from the hobby store or Texas Art Supply. The photo shows an outdoor paint – not the best option, but it’s what I had in the truck. 🙂 I use a small rectangle of sponge dipped in water and then in the paint.
For extra assurance, on thick papers, dark surface printed on a white backing, you can also use artist’s chalk pastels (chalk only and NOT oil pastels) to color the edges of the seams. Do a Search here (upper right corner) to find previous posts about that.

Bold David Hicks Geometric in Garden Oaks Powder Room

December 18, 2021
This young family wanted some WOW! Factor for their new home’s plain-Jane powder room. It’s a 2-room set up, with the sink in one area and the toity around the corner in a more private area.
Looking through one room into the next – yes, really a WOW! Factor!
Looks fantastic with the burnished gold faucets, light sconces, and hand towel ring.
Opposite wall. I centered the pattern on the wall opposite the mirror, so that the design would work around the room evenly and the pattern would fall equally on these two walls. In other words, the pattern hits the tile wall on the left at exactly the same point as it does on the tile wall to the right. The sconces also land on the same element in the wallpaper. This gives a very symmetrical look as you face the mirror. One of those things no one can put his finger on, but it makes the whole room feel balanced and in sync.
Back wall connecting to right wall with door that leads to the entry hall.
The commode room is under the stairway, so has a strongly sloped ceiling – and tight working quarters. You can also see that the wall is bowed in the corner, resulting in a good pattern match at top and bottom, but some mis-alignment in the center. Pretty typical. No walls are perfectly plumb, no ceiling is perfectly level, and corners are just about always a bit wonky. Geometric designs like this are particularly difficult to make look perfect.
On close-up, you can see a slight raised ink texture. This surface printed wallpaper was not a crisp look – nothing wrong with that … it’s part of the hand-crafted look. The non-woven material is thick and stiff, and the seams were a bit more noticeable than on many other non-wovens. I also noted that where the gold ink hit the edges of the paper, there were ever-so-slight curls and overlaps. My guess is the gold ink reacted to the wet paste and expanded differently from the black and the background color. Never mind. From two feet away, you can’t notice it at all.
The David Hicks Collection by GP & J Baker contains several variations of this type of bold geometric pattern. Some of the vendors are calling this a “new” release … but I first hung one of these designs maybe 10 years ago.
Unfortunately, they haven’t gotten any better with the quality. Surprising, because GP&J Baker’s papers are usually very nice – I did one just a few months ago and loved it. Conversely, this one is quite stiff, and trying to work it into tight spots such as corners or behind a toilet or around a vanity or light fixture can result in creases. And the ink flakes off very easily. Here, just pressing the wallpaper against the baseboard so it could be trimmed caused the ink to chip off, and you can see little bits of it collected on top of the baseboard on the left. Luckily, this was at the floor and not very noticeable. I used some black chalk to cover the white areas. But at eye-level, this would have necessitated removing the whole strip and replacing with a new one.
