Geometric on Tricky Outside Corner

March 21, 2023
OK, never mind the ’80’s-era toilet paper holder that’s recessed into the wall here and is not removable – which presents a challenge all its own. My issue is adding the next strip of wallpaper to the left, turning the corner, and keeping the pattern matched as well as possible in both the inside corner and around the outside corner.
Usually, when turning inside corners, you wrap the paper around the corner 1/8 of an inch, and then cut a new strip of paper, match the pattern, and then overlap it that 1/8″ . That helps eliminate issues like mis-matches or wrinkles due to crooked corners or uneven / bowed / out-of-plumb walls . (no walls are ever perfect )
But in this case, we also have an outside corner to wrap. Even though it’s only about 2″ wide, that edge can cause the pattern to go off-plumb , or to create wrinkles in the wallpaper .
Going against most rules of wallpapering , I’ve decided to wrap the next strip around this 2″ wide wall and then onto the wider wall to the left .

Here I am, starting to position that next strip. I’m not going to try to wrap a full 27″ wide strip around this turn. Instead, I’ve trimmed it vertically along a horizontal stripe , which makes this strip narrower and more easy to handle , and also will help in placement of the next strip.
Now I’m pushing it into place into that corner. Note how the paper is wrinkling, both on the wide wall, and as it comes around the 2″ wall.
Another shot of the placement and wrinkles .
Using my plastic squeegee smoother to press the paper tightly into the inside corner. Note that, since the corner isn’t perfectly straight or plumb, there were a few areas where I couldn’t press the paper tightly into the wall, but had to leave a bit of a gap or air bubble, in order for the left edge to wrap around the turn.
The plastic smoother can also be used to gently push out wrinkles on the larger body of the strip of paper to the right. Don’t press too hard , nor overwork , because you don’t want to stretch the paper – that will cause more wrinkles.
The plastic smoother took care of the inside corner. Here I’m using my damp microfiber cloth to tightly press the paper around this outside corner .
OK. Paper’s wrapped tightly around this corner – but, because the corner isn’t straight , we’ve got wrinkles and warps .
Sometimes, you need to take a scissors to make relief cuts to help ease the paper around the corner . Try to make your cuts along an element of the design , to make the slit less noticeable.
here is that little narrow bit, finally wrapped around the outside corner. Now we need to add the next strip to the left of this. Note that this narrow strip isn’t straight nor plumb nor equidistant from the corner that we just turned. Nor is it equidistant from the next corner we have to deal with, which is to the left (not pictured).
Since we want the wallpaper strips to match in the corners, it’s important that the wallpaper pattern fall in the corner to the left at the same point from ceiling to floor. Complicated to explain.
So I’m taking a fresh strip of wallpaper , made sure the pattern matches correctly , and have trimmed it vertically along the tan stripe . Now placing it along this wrapped edge.
Because I’m overlapping instead of butting , I’m able to pull the new strip to the right or left, to keep it equidistant from the right outside corner . Or, from the inside corner to the left.
Actually, I don’t care much about the right side. The eye won’t notice if the new strip isn’t perfectly plumb . Nor will it notice if the pattern match isn’t 100% perfect . But it will notice if the pattern doesn’t match perfectly in the inside corner to the left.
So I’m pulling and manipulating and overlapping the strip a bit, so that the left edge of it is exactly 10-3/4″ from the left edge. This ensures that the pattern motifs fall all at the same point into that corner on the left.
Do I can cut my next strip, trim it vertically so the design matches with that in the corner, and get a perfect pattern match in the corner. Kinda difficult to explain, but I hope you can follow what I’m describing.
Note that this overlap is causing a bit of a ridge under the paper . Hard to see here, but when the paper dries and shrinks tight against the wall, it will be a little more obvious. But I’d rather have a ridge on the right, than a pattern mis-match in the corner to the left.
Oh, and never mind that little pattern mis-match to the right … that’s the paper wrapped around the corner, so you’re looking at different dimensions, not a pattern mis-match.
Here is that strip finished. The vertical strips isn’t perfectly plumb, but no one can tell that.
ut the pattern is perfectly straight in the inside corner to the left . So when I take my subsequent strip and trim it vertically to remove the right edge by approximately 10-3/4″ , the pattern should match perfectly in this inside corner. (It did!)

Plumbing Up Coming Out Of A Corner DRAFT

January 29, 2023
Here I’m hanging wallpaper, moving from right to left, preparing to turn this corner . You don’t wrap a strip of wallpaper around an inside corner (see previous post for more information). So I’ve cut a new strip, trimmed off excess on the right so the pattern on the new strip matches that on the existing strip, and am getting ready to proceed to the left.
But corners are never straight or plumb , and chair rail and ceilings are never perfectly level . So if I butt the new strip right up into the corner, if that corner is off-plumb , it will cause the new strip, and all subsequent strips, to be off-plumb. And that means that the design motifs will start tracking up or down hill as we move across the wall.
You want all the motifs to be at the same height along the ceiling and chair rail – within reason, of course, because if those features are not level, the motifs can’t help but move up or down.
Anyway, the best you can do is to hang your new strip perfectly plumb . So here you see I’ve shot my laser level at the wall at the far edge of the new strip. I’m butting my new strip up to that red line. I’m also using my 2′ bubble level as an extra guide.
Note that sometimes this means the new strip will not butt up perfectly in the corner, because it may tilt a bit to the left or right. When that happens, you just trim off the slight overlap. This means you may end up with a slight pattern mis-match in the corner. Usually not too noticeable.

What’s A “Fat Cut” ?

January 28, 2023
Here, I’m hanging paper from right to left, and have just come around a corner , which is in the center of the picture. You almost never wrap wallpaper around an inside corner . Corners are never straight , and the paper will buckle in the corner . And the edge will not be straight , nor plumb , and thus the next strip won’t butt up perfectly against it . And it’s also probable that the strip will torque off either up or down, causing your pattern to creep up or down the ceiling and floor lines.
The answer is to stop the strip of wallpaper in the corner , and cut a new piece for the subsequent wall.
But you can’t just trim tightly to the corner. Because most likely there will be gaps (remember I said that corners are never straight?), so some of the wall will show.
So what you do is wrap the paper just a teeny amount around the corner , and then overlap your new piece over that. This does mean that you will lose some of the pattern in that overlap.
I can’t stand that pattern mis-match, so most of the time, the way I do it, I’ll take a fresh strip of wallpaper for the next strip (to be placed on the left in the photo) and trim it so the pattern matches as perfectly as possible. But I’m getting ahead of myself. Back to the fat cut …
In the photo, I’ve cut my strip on the left 1/2″ wider than needed to fit this wall. I don’t want this 1/2″ of wallpaper under my overlapped new strip, because the leaves a visible ridge. But you do want a little underlap, because you need that to prevent a gap from showing in the corner.
So in the photo, I’ve trimmed off most of that 1/2″ and trimmed it down to an unnoticeable 1/8″. How on earth can you get a trim that thin and that consistent?!
I use this handy metal plate with a rolled edge (on the left).
This plate has bends and other edges of other thicknesses , rounded edges , won’t leave marks on wallpaper, so it has many uses.
Here’s a close up of the trim guide edge that allows for that 1/8″ fat cut .
Back side of the plate. (Don’t mind the blue tape – it’s just there temporarily.)
This edge is a little thinner , and would cut too close for use in a corner. But it does have a use if you need a trim in an area where you don’t want the paper trimmed tightly into the edge / corner.
You’re looking at where wallpaper meets crown molding. This join edge has gaps between the molding and the wall in some areas, and other areas have gunk and uneven areas. Trimming with my usual trim guide would cut too close and let some of these icky things show. So here I’ve used the thicker trim guide. As you can see, it allows the wallpaper to wrap ever so teeny much of a bit, so it covers the bad area, but doesn’t creep onto the molding.
Here’s another example, along door molding. At the top, I used my usual thin trim guide (see below). But this allowed a bit of a gap to show, due to decades’ build up of paint , caulk , dirt , etc.
So, midway, I switched to using the steel plate as a trim guide. This made the cut just fat enough that the wallpaper wrapped a hair and covered the icky area.
Here’s my usual trim guide . I’m guessing it’s about 9″-12″ long .
You can see that the edge is very thin . In most cases, this is ideal, because it allows for good, tight trims right smack into corners and edges.
That steel plate shown above was invented by a colleague in the Wallcovering Installers Association ( WIA ) . They are all the same length, but they come with three different degrees of angles , and can be used for lots of wallpaper installation tasks .
The colleagues has them manufactured and then sells them to us paperhangers . She sells other cool tools , too.

I Did Not Hang This Wallpaper. How Do I Know?

June 20, 2019


I hung wallpaper in several rooms of this house back in the ’90’s. I thought the homeowners said that I had hung this bathroom, too. But once I got to looking more closely, I knew that I had not.

Top photo – hard to see, but the wallpaper had been wrapped around the inside corner. Wallpaper strips are supposed to be measured, and then split in two vertically, so that one half of the strip wraps a wee 1/8″ or so around the corner. Then the second half of the sheet is hung on the new wall so that it overlaps that 1/8″ bit, and then continues on along the wall.

Also in the top photo, to the right of the corner, the pooching seams on this vinyl wallpaper are probably caused by moisture in a humid room (do a Search here to learn more, or read my page to the right). But I do think that if the original installer had used a more appropriate primer, the paper would have performed better.

Photos 2 & 3 – Some papers can get soggy when wet with paste and become difficult to trim. But, gee, I do hope that I would never leave a homeowner with torn, jagged cuts like this.

Likewise with Photo 4 – See the patch above the window molding and the splice above the backsplash?

Photo 5 – Trimming along shower edges like this is difficult, but I would endeavor to give a straighter cut than the previous installer did.

Last photo – Not my handwriting, not my terminology, and, OMG, my father would roll over in his grave … definitely not my spelling!

Narrow Strip Coming Out of a Corner

August 28, 2018


See that narrow 3/8″ wide strip of wallpaper sitting on my table? That is to be my first piece coming out of this corner.

When you hang wallpaper around an inside corner, you don’t wrap it around the turn, but, rather, split the piece vertically so it wraps 1/16″ around the corner. Then the strip that you cut off is hung on the next wall, butted up into the corner. This avoids twists and wrinkles and bubbled areas caused by walls and corners that are not perfectly straight or plumb.

But when the piece that is to be the first strip on the new wall is this narrow, it presents problems, because it’s very likely to not hang straight, and you can’t hang the next strip of wallpaper against a crooked edge because you will get gaps and overlaps.

Adding to the dilemma is that this narrow strip had already been pasted. I had finished for the day, and intended to hang the window wall to the left the next day. The strip was already pasted, but I couldn’t hang it because of the aforementioned issues, plus, you are supposed to hang a whole wall at a time, because all of the strips have to “meld” together – you can’t hang a wet piece against a dry piece.

My solution was to wash the paste off this narrow strip, and hang it up to dry overnight. I just had to hope that the water would not cause it to expand too much, or warp, or other.

The next day, I pasted this narrow 3/8″ wide strip, along with the strip that would be placed next to it. Then I hung them together, as if they were all one piece of wallpaper. That way, I could work them into the corner snugly, and keep the seam between them nice and tight.

When coming out of corners, it’s common for the wallpaper to go off-plumb, because the corner might be out of wack. So you can (barely) see the red line of my laser level on the left edge of the strip of wallpaper, ensuring that the new strip falls plumb.

Wonky Walls = Mis-Matched Corners

April 29, 2018


When wallpaper turns an inside corner, you split the strip vertically and place the first half of the strip so that just a teeny tad wraps around the corner, and then you overlap the remaining strip into the corner, using a level to plumb this strip. This keeps all your subsequent strips nice and plumb, and running straight at the ceiling and floor lines (assuming that these lines are truly level).

But when walls and corners aren’t plumb, wallpaper patterns will get distorted. The rule of thumb is to match the pattern at eye level, and then let it fall as it will above and below that point.

This pattern is busy enough that the mis-match is not all that noticeable.
