1/2 Inch Width = A Full Strip

December 15, 2022

I’m fixin’n to hang faux grasscloth on this accent / headboard wall in a master bedroom in the Spring Branch area of Houston. The textured wall has been skim-floated , sanded smooth , primed , and is ready for wallpaper .
The material is 20.75″ (20 and 3/4″) wide . So here I’m measuring off how many strips of wallpaper I’ll need.
I’ve counted out seven strips across the wall, and have come to my last (8th) strip. Look at my pencil mark – it’s at 21.” Remember that the paper is 20 3/4″ wide. This means that, to cover that last, scant 1/4″ width , I’ll have to use a ninth strip. Which will be a whole 9′ high strip that’s 20.75″ wide.
Useing a 1/4″ wide strip off a 9′ long length leaves us with a whole lot of waste – paper / square footage just going into the trash.
This is, again, why you should not purchase wallpaper based on square footage. It’s more a matter of determining how many strips you will need – factoring in the pattern repeat, etc.
Even better , have the wallpaper installer make a site – visit and calculate for you.
Going a step further … Since this is a (faux) grasscloth and has not pattern match , the seams will all be visible . So we try to balance the panels on the wall. Meaning, the wall will look better with panels of equal-widths, instead of, for instance, eight panels at 21″ wide and one at 1/2″.
For the record, it also looks better to not have a seam fall at dead-center on the wall. Better to have that center panel straddle the mid-point.
With this particular install, that’s what I chose to do. I took the first (let’s just call it 21″ wide for ease) … I took the first 21″ wide panel and used my laser level to line it up so 10 1/2″ fell on either side of the center line on the wall. So, this first panel was straddling the center line.
From there, I used full-width (21″) panels one either side.
Until I got to the last panel on the left, and the last one on the right. These two ended up each being about 15″ wide. So I had seven panels that were 21″ wide, and then two flanking on either side that were 15″ wide. This gave the wall a nice, balanced, uniform look.
Yes, I could have hand-trimmed each strip to 19″ wide or whatever the math would have worked out to. But my option was simpler, faster, maintained uniformity between the majority of the panels, as well as uniform width on the two outer panels, eliminated the worry of gaps at the seams due to unevenly trimmed rigid vinyl goods, and the 6″ width difference wasn’t very noticeable. And, also, since this was a faux grasscloth and color variations were minimized, you could hardly see the seams, nor the width of the panels, anyway.
From 5′ away, this wall looked perfectly homogeneous .

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.

Reverse-Hang Wallpaper Strips for Uniform Color

May 1, 2022
Here I am trying to find and understand the pattern match on this very difficult to see faux reptile pattern.
All this is more confusing because the little box toward the left on the bottom of the manufacturer’s spec sheet says this is a drop / offset match. It is not – it’s a straight match .
The instructions also say it’s 64cm (25 in). That’s not true, either. It’s more like 12.5″
The pattern also repeats itself once horizontally across the strip.
Found the match!
Problem is, when I followed the manufacturer’s instructions and hung the material as a matched pattern, I got paneling . This means that the material is darker along the left edge than along the right. Therefor, when you place one strip next to another, you see an abrupt color change , as shown in the photo.
The pattern may match, but this color variation is pretty unattractive.
So I followed what’s pretty standard protocol for textured and natural materials (such as grasscloth , paperweaves , cork , etc. and even this vinyl .) I took that strip off the wall, repasted it, and hung it again – but this time upside down.
By doing this, you’re hanging the left side of one strip against the left side of another strip. Because it’s meeting up with itself, there is no or minimal color difference.
Hard to explain, and if I could figure out how to draw some arrows or diagrams …. well, I can’t, so you’ll just have to try to follow along.
Bottom line – you hang one strip right-side-up and the next strip upside-down . Keep track of which is the top on each of your wallpaper strips, and mark on the wall (in pencil) which direction each strip should be hung.
Made by Super Fresco Easy , called Crocodile . Really nice material, and affordable.

Run Numbers Matter – More

April 19, 2022
When you hang wallpaper, you need to make sure that all the rolls / bolts are from the same Run Number / Batch Number / Dye Lot. This means that the rolls were printed at the same time from the same batch of ink.
Another batch of ink that’s mixed up and then printed a few weeks later may be a very slightly different shade. You can easily see that color difference in this photo.
Placing strips from two different runs next to each other on the same wall will result in a subtle but unpleasant striped effect.
Besides the color differences of the ink, the printing press can be positioned differently, too.
Look at the bottom strip, at the left of the photo. The vertical line on the left is wide.
But now look at the strip on the right, which is on top. It’s from a different Run.
Here the vertical strips is narrow.
If strips of wallpaper from these two different runs were placed next to each other on a wall, not only would you see a color difference between them, but you would have an unpleasant striped effect, because one vertical stripe element in the design would be unnaturally wide, and another would be much narrower. In between would be other stripes that are the standard medium width.
Very un-uniform and very un-pleasing.
Before any wallpaper rolls get cut, pasted, and stuck to the wall, check to be sure the run numbers are all the same!

Balancing Strips of Grasscloth to Fit Wall

November 23, 2020

With grasscloth or other products that mimic it, where the seams and individual panels will be visible and obvious, I like to “balance” the width of strips and the placement of seams, so they fit onto the wall in a uniform and pleasing way.

Often this means I have to trim the strips of wallpaper vertically, so they will all be the same width.

In this photo, you see a bit of that process.

Flooded Home is Finally Finished, and a Moroccan Trellis is the Finishing Touch

July 20, 2019


I’ve worked for this family several times over the last 25 years. Unfortunately, their home overlooking Braes Bayou (south central Houston) was flooded during Hurricane Harvey. The original home was torn down (along with my beautiful wallpaper ! 😦 ), and a new, raised home was built. Today I hung wallpaper on an accent wall in the dining room.

Photo 1 – the wall as the contractor left it

Photo 2 – the wall after I have primed it

Photo 3 – finished

I don’t like true grasscloth due to the visible seams and very noticeable color variations between strips, and also it’s propensity to stain easily. (Read my page to the right.)

The product pictured above is a fantastic alternative to real grasscloth. It is paper, superimposed with a vertical string material, so it has the texture and dimension that people are liking these days. The grass design is printed on (not real grass fibers), and this keeps the color uniform, so no abrupt color differences between strips.

The pattern can even be matched from strip to strip, making the seams pretty much invisible. You also have the option of not matching the pattern, to give a look similar to real grasscloth. Even then, the consistence of this design and color make it pretty impossible to tell where the seams are, if you are standing even three feet away.

In addition, the material has been treated, so it is somewhat resistant to stains.

I’ve hung this faux grass a good number of times, but this is the first time to hang it with the trellis design. The homeowner likes to mix modern with traditional, hence the geometric pattern with the antique furniture and chandelier. She also hunted for something that would meld nicely with the color of the paint on the woodwork. I like the look a lot.

This wallpaper pattern is by Wallquest, in their EcoChic line, and I believe in the Grass Effects book. It was bought from my favorite source for good quality, product knowledge, expert service, and competitive price – Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby.

Wonder Faux Grasscloth Finishes off a Flood House Rebuild

July 15, 2018

If this room looks familiar – it should… This week I’m working in a home in the Meyerland area of Houston where I hung paper after the home was repaired following flooding during the Tax Day Flood in April 2015. This home was flooded again during 2017’s Hurricane Harvey. The homeowners wanted everything exactly the way it had been before the flood.

This paper went on one wall in the entry.

I LOVE this product! I HATE real grasscloth (read my page to the right, and do a search here to learn more), so when people even breathe the word, I steer them to this instead. This is a printed paper product, so it has a pattern that that can be matched, so you will not have the abrupt visible seams that come with real grasscloth. The color is uniform, so no worries about the disagreeable shading and paneling (color variations) that are rife with the natural grasscloth products.

And the manufacturer has attached vertical strings, which add a natural element and a textured effect that people are craving these days. It’s reasonably priced, too.

Same Run – But Color Difference

June 8, 2018


One of the first things the installer does before starting a wallpaper job is to check the run numbers, to be sure it is the same for all the bolts of paper. This means they were all printed at the same time with the same batch of ink, so they will all be uniform in color.

Both these bolts are from the same run. But look closely, and you will see that the blue lines on the strip to the right are darker and thicker than those on the left. If these two strips of paper were placed next to each other on the wall, the difference would be very visible.

I am glad I noticed this before I started cutting any strips. I set aside the errant bolt, and hopefully won’t have to use it (I always have my clients buy a little extra, for repairs later and in case of instances like this). If I do need to cut into this bolt, the bathroom has a lot of choppy areas that are on separate walls where the color difference won’t be noticeable.

A Beautiful, Natural Grasscloth

May 16, 2018


I was really pleased with the grasscloth I hung today. The fibers were thin enough that the material was pliable and turned corners well. The texture was a pleasing middle ground between rough and refined, and the color was gorgeous – natural, with bits of brown, gold, grey, and olive all mixed together homogenously.

But best of all, the material had virtually no shading or paneling or color variation issues. Do a Search here (upper right) on these terms to see what most grasscloth looks like, and why I am not a fan of it. But this stuff today – I liked it!

Because there is no pattern to be matched, you will see all the seams. But because the color and the texture were quite uniform, the seams and panels pretty well blended together. The two shots showing the seams are good examples of what grasscloth is supposed to look like.

The room immediately felt warmer and more inviting, with a bit of color and texture from the natural material on the walls.

I don’t know what the brand is, because the label simply said “Wallcovering.” But it was bought at below retail price from Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby.

I hung this in a bathroom in a newish home inside the Loop in Houston. Yes, grasscloth will stain if it gets splashed with water, so it’s not recommended in wet areas. But the homeowner is a single gal, and she promised to use the room gently. 🙂

She also promised to keep the door closed, so the cats will not get their claws into the new textured wallpaper.
