1 3/8″ Wallpaper Strip

February 2, 2023
Arrgh. This last strip of wallpaper in a master bathroom ended just shy of the shower tile surround . That’s a 1 3/8″ gap that needs to be covered with wallpaper. I’ve filled in pieces narrower – like, 1/2″ or less. But, still, it’s a PITA, and takes a lot of time.
And it will require a full 9′ strip of paper, just to cut off this 1 3/8″ wide bit from the right side. So a whole lot of unused paper is going in the trash can. As I like to emphasize, always purchase a little extra.
I don’t usually pre-trim strips in this situation, because walls are never straight so it’s hard to get the width perfect. And the fact that wallpaper expands when it gets wet with paste , so your pre-trimmed strip may end up wider than the space. And because trimming the piece while it’s on-site gives a better, tighter fit.
Anyway, this time I did pre-trim. I measured carefully, and found that most of the space was 1 3/8″ wide. But three artichoke motifs up from the floor (about 2 1/2 feet), the width widened to 1 1/2.”
So I used my straightedge and fine ruler and trimmed accordingly. The pasted it and let sit for a few minutes.
Here I’m smoothing the strip into its little narrow gap.
Finished.

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 .

Wasting a Lot to Get a Little. A Lesson in Pattern Repeat. AKA: Don’t Order Wallpaper Based on Square Feet DRAFT

November 27, 2022
This is the tail end of a roll, and is too short to use on a full-height wall . So I save these pieces for use over doors , under windows , etc. (I never throw scraps away until the job is finished.)
This piece is about 3′ long . I need a piece 8″ high to go over a door . In order to get the right pattern match , I have to cut my 8″ piece from about the center of this 3′ long scrap . As you can see, that leaves us with more than 2′ of length of wallpaper that cannot be used . It’s too short to fit most spaces , plus the pattern repeat is not in the right position.
Let’s see … roughly 2.5′ of length multiplied by the width of the paper (27″ but we’ll call it 2′ for ease of mathematics ) comes out to 5 square feet of wallpaper . That cannot be used anywhere. It just goes on the scrap pile.
This is another example of why you can’t order wallpaper based on square footage . Wallpaper isn’t like paint – you can’t use every square inch. You have to plan for the waste factor . And the waste factor changes, based on the length of pattern repeat juxtaposed against your wall’s height .Most websites that sell wallpaper mention the square footage of a roll / bolt . But they fail to give adequate information on how to factor in for accommodating that waste . Some say to add 1% or even 10%, but that’s not adequate . What to do? Contact the wallpaper hanger / installer before you order your paper!
This cheery pattern is by Rifle Paper , made by York . Rifle is very popular right now. And now wonder – those flowers and visual movement are mighty attractive !

Artemis Block – Inverted Twin of Yesterday’s Install Post

October 14, 2022
Half bath sink room primed and read for wallpaper . I have plotted where the seams will fall and striped with dark paint , to prevent the light colored primer from showing in case the seams gap a bit.
Artemis is available as a floor-to-ceiling pattern. So this partial coverage option is an innovative and fun variation on a theme .
This is the same pattern Artemis Climbing Walls as yesterday, but reversed , so the flowers go from bottom upward .
The ceilings are pretty high. The empty 5 gallon bucket is there on the counter (with non-slip cushioning beneath it) as an un-OSHA approved footrest , so I can safely reach the top corners .
Artemis is a very popular wallpaper pattern , especially in this dark / black colorway .
Manufacturer is House of Hackney .
This install was on four walls in a powder room , instead of a single accent wall. Since this comes as a 4-panel mural instead of traditional rolled goods, the layout was a little more tricky . I cut out the little mock-ups from the instruction insert, and marked them as to roughly where each panel was separated .
This is a non-woven material, and can be hung by the paste the wall method, as I did yesterday in the dining room. But today, in the small and chopped up powder room , I opted to paste the paper instead.
You will note that this pattern continues uninterrupted from one mural to the next. If you have a wide space to cover and will need more than one mural , this continuation of the design is imperative. Not all do, so check and be extra sure, before you order.
Speaking of ordering material … remember that for murals, you MUST add 2″ to EACH side – in other words, a total of FOUR INCHES to BOTH WIDTH and HEIGHT . This will accommodate trimming at floor and ceiling , and also will allow for wonky or off-plumb / level surfaces .
Better yet, have your wallpaper installer calculate for you.

Need a Seam Down the Middle

August 17, 2022
See how that wall is 38″ wide? And the bolt of grasscloth is 36″ wide?
So two strips of wallpaper are needed to cover this wall.
You don’t want a 36″ wide piece and then a 2″ wide piece. Much better to have both strips the same width. This makes each strip 19″ wide, with a seam centered down the middle.
Much more pleasing to the eye.
Note that it does take extra paper to do this, because the 17″ wide leftover strips can’t be used anywhere else.
But the overall visual symmetry is worth it.

Dark and Moody Bedroom Accent Wall

August 4, 2022
The wall has been skim-floated and sanded smooth , primed , and is ready for wallpaper .
The homeowner did a great job coordinating the wall and ceiling paint with the colors in the wallpaper.
This is a room that’s made for sleeping!

At first I thought the pattern scale was too small for the large wall. But once I saw it on the wall, I really like the way it fills the space.
To me, this pattern has a sort of calico look.
Close-up shows the light texture on the paper.
This is a non-woven material, so I’m installing via the paste the wall method . Here I’ve cut and arranged all my strips in the order in which they will be hung . This is a drop match pattern , which some folks think of as A and B strips. Meaning, for instance, an orange flower appears at the top of the wall on Strip A . But the next strip, Strip B, has a yellow flower at the top. When you get to the third strip, we are back to an A and an orange flower. Next comes another B strip – and so on.
I’ve rolled the strips backward , with the top of the strip coming off first. This will prevent the printed face of the wallpaper from bumping into the pasted wall during installation .
Wallpaper often shrinks a tad when the paste dries , and this can result in very minute gaps at the seams . With dark wallpapers , it’s pretty important to take steps to prevent white from showing at these gaps. Here I’ve measured out where each seam will fall, and taken diluted black paint to make a dark stripe under each seam . I don’t make the paint full-strength, because wallpaper paste isn’t formulated to adhere to paint. I want the wallpaper adhering to the primer I’ve applied. That’s also the reason why you don’t want to roll paint over the whole wall.
Also, I have only striped some of the seam areas, and will wait until some strips are up on the wall before striping more lines. This is because wallpaper expands when it gets wet with paste, which can make it difficult to plot the exact width of each strip as you move across the wall.

I use acrylic craft paint from the hobby store, applied with a bit of sponge. I keep a small dish of water to dip the sponge into, which dilutes the paint a bit.
You also see a stick of chalk pastel . See next photo.
Besides the wall peeking out from behind the wallpaper seams , it’s also possible / probable that the white edges of the wallpaper backing / substrate will show at the seams. I take a stick of chalk and run it along the edges, making sure to apply from the backside, to avoid getting chalk onto the surface of the wallpaper.
Be sure to use chalk pastels and not oil pastels – oil will bleed and stain wallpaper. Some installers use liquid paint or markers – again, be sure to use water-based or acrylic , and never oil based or permanent markers .
BN Walls is the brand. Altogether, this was a pretty nice product to work with. It was thin and very soft and flexible (many non-wovens are not).
I wasn’t happy with all the seams, though. I believe the paper was cut with dull or wobbly wheels at the factory, because the edges seemed to not be perfectly straight . So I ended up with gaps and overlaps in some areas. Here you can see the wallpaper edges pouching up a bit due to excess paper.
But, as I mentioned, this material was quite flexible, so it was pretty easy to spread these edges apart an use a tool to push them apart and then down to prevent them from pouching up again. Once the paste started to dry, these areas held nice and tight and flat.
This is a townhome in the Rice Military neighborhood of central Houston .

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.

Dark Wallpaper – Preventing White Gaps Showing at Seams

February 24, 2022
Dark papers are popular right now. But since wallpaper shrinks a tad when it dries, and since it’s usually printed on a white substrate, it’s possible that hairs’-breadth gaps of white wall may show at the seams. One way to prevent that is to stripe the wall under where the seams will fall with a color similar to the background of the wallpaper. Be careful to not get it too dark, as too much pigment may interfere with the wallpaper primer’s ability to perform optimally.
I measured the width of the strips, and then used a laser level to guide my stripes.
I use craft paint from the hobby store, and daub it on with a scrap of sponge (right) and dip into a bit of water, which I keep in a Gatorade bottlecap (left).
To get rid of the white edges of the substrate, I use a bit of chalk (some folks use paint – but make sure it’s water-based …. NEVER use oil-based paint, markers, or chalks, as they will bleed onto the surface of the wallpaper). I run the chalk along the edge of the wallpaper strip, making sure to work from the back side, to prevent the chalk from working its way onto the surface of the wallpaper. Use a light touch, but cover all of the white edge.
Finished wall. Don’t see no stinkin’ white gaps! 🙂

Wallpaper in 2-Panel Set (Mural)

June 1, 2021

Re my previous post, this wallpaper came as a sort of mural, packaged as a 2-panel set. Each “roll” contained an “A” (left) strip and a “B” (right) strip.

Because the strips are only 18″ wide, and only two 9′ long strips are included per bolt, the paper covers a bit less wall space than traditional papers.

What’s nice is that the panels match from left to right and from bolt to bolt. This makes it possible to cover any width you want. (Many murals come at a set width and height, and do not continue from one to another, so you are locked into the manufacturer’s width and height.)

Here you see me laying out the “A” and “B” strips. And also how the panels come wound up in one long strip of paper, and the point where you cut the two strips apart.

Balancing Grasscloth Panels

January 18, 2020


Because grasscloth does not have a pattern that can be matched, the seams are always visible. And, due to the characteristics of natural materials, the strips will have color variations within themselves. This means that you will distinctly see each individual panel on the wall.

Because each panel is noticeable, walls usually look better if each panel is the same width. In other words, on a wall 14′ wide, it looks better to have five strips that are each 33.5″ wide, rather than four strips that are 3′ wide and one that is 2.’

In addition, grasscloth invariably comes with edges that have been abraded during shipping. On top of that, it’s common to have color issues at the edges – either a light band, or a dark band, or irregular bands of shading along the edges.

For that reason, many paperhangers trim the edges off both sides of each strip of grasscloth. This allows the installer to trim the width to fit the wall’s dimensions, it gets rid of most of the damage caused by shipping and handling, and it reduces the shading that the manufacturer’s dye process may have left along the edges.

If you study the photo closely, you will see that all these panels are the same width.

And, while some jagged color variations do appear along some of the edges, it is not pronounced, as the darkest areas have been trimmed off.

There is still a color difference between the three strips on the right and the four strips on the left – but that is just the nature of grasscloth and its manufacturing process

As you can imagine, all this measuring and plotting and trimming takes extra time. If you’re like me and like math and geometry and logistics, hanging grasscloth can be a whole lot of fun!
