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.
