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.

Trick to Make Getting Around Pedestal Sink Easier

February 20, 2022
Hanging wallpaper in powder rooms often means working around a pedestal sink. It’s sooo much easier if the sink is not in the room. But that means the homeowner has to pay a plumber to come remove the sink, and then come back and replace it after the paper is up. This risks damaging the new paper, causes damage to the wall that I will have to repair. And costs several hundreds of dollars. So I usually get the paper up with the sink in place.
That means you have to wrestle a 9′ strip of paper over the sink, then down the narrow space on either side (on the right in this photo), and then underneath it. This opens the possibility of creasing the paper, tearing it, or other damage.
I’ve developed a trick to make it easier.
I’ll cut the paper horizontally a few inches below the top of the sink.
When possible, I cut along design elements, to help disguise the cut.
Here I’ve hung the paper above the sink and down the right side. Now I have to get the paper on the lower wall portion.
But it’s a lot easier because the sink is out of the way. Here I am getting ready to position this bottom section.
All in place. Next I will do the same with the area to the left of the sink. Things don’t always meet up perfectly at the seam, so you may end up with a gap or overlap or a pattern mis-match. But it will be behind the stand / base of the sink, so not noticeable.
This pattern is by Milton & King. It’s a non-wove material, which is a lot stronger and tear-resistant than a paper wallpaper.

” Shrinking ” a Strip to Make for a Good Corner

February 5, 2022
I’m hanging wallpaper moving from right to left. The wallpaper is 21″ wide. The width between my last strip (over the door) and the corner is 19″ wide. This means that my next strip is going to wrap around the corner by 2″.
This is not good. You never want to wrap wallpaper around an inside corner, especially a tiny amount like 2″. Corners are never straight, and thus the wrapped bit will be warped and un-straight. The next strip will never butt up correctly with it, leaving gaps and overlaps. You will also end up with a new strip that is not hanging plumb.
Also, wrapping around corners doesn’t allow for movement in the corner as the temperature changes in the room, or as the house shifts on its foundation.
The goal is to wrap the corner by about 1/16″ – 1/8″, and then overlap the new strip on top of that narrow wrap.

This is how I want my strip to land in the left corner.
Bottom line – if I want my next strip to wrap just 1/8″ around the corner on the left, then it’s going to overlap by 2″ onto the existing strip on the right. If that happens, we’ll lose 2″ of the pattern and have some eye-jarring cut-off pattern motifs.
So, somewhere, I need to “lose” 2″ of paper. Looking at the short seam above this window, I see where I can remove some paper without messing up the pattern too much.
I’ve removed the strip and used my straightedge and a razor blade to slice off 3/4″ of paper.
The blue plastic is there to keep paste off my table, and the shiny thing is a protective plastic strip I use to keep from cutting into the wooden table.
3/4″ removed.
Slid back together, you don’t much notice the very minor pattern mis-match created by the absence of the narrow strip.
This could work on a longer strip as well, depending on the pattern motifs.
Now the left corner is how I want it.
But the right edge of the strip is overlapping 1″ or more over the existing strip over the window. You can see there is a pattern mis-match, not to mention a bump where these two pieces overlap. So I’m going to do a double cut and splice these two strips together.
Splicing means you press hard to cut through both layers of wallpaper. Your blade will probably cut a bit deeper and dig into the wall, scoring the surface. This is bad, because an un-intact surface can give way when wallpaper paste dries and the material shrinks, tugging at the surface. This can actually cause layers of the wall to come apart ( delaminate ), which means the wallpaper will come up at the seam. Do a Search here to learn more.
To prevent this, I’m using a Boggess Strip (a clear, thin, flexible strip of polycarbonate Lexon plastic padding ) to put under where the splice will take place, to protect the wall. You can’t cut through this stuff!
The strip in place.
I’ve smoothed the left strip back into place overlapping the existing strip. Next I’ve used a short straightedge and a sharp (important) new (important) single edged razor blade to slice through both layers of wallpaper. Here I’m removing the top strip of excess cut-off paper.
Now I’ve pulled back part of the strip on the left so I can remove the excess wallpaper on the bottom. Note that the cut is a little uneven in areas, to cut around the leaves in the design.
Removing the Boggess Strip. This does put tension on your wall, so you’ve got to have a good wallpaper primer underneath, applied over a sound surface.
The two strips smoothed back together.

I used a pencil to touch up the edges of the leaves, to make them look more rounded and natural.

Wrapping Wallpaper Around an Unstable Corner

February 3, 2022
I’m not sure what’s going on in this corner over a shower. But it looks like maybe some foundation movement has caused shifting in the corner, and the painters have used caulk to bridge a gap.
When you hang wallpaper, you don’t wrap a full sheet around an inside corner. You wrap about 1/16″ or 1/8″ around the corner, and then cut the strip in two vertically, and overlap the new cut piece on top of that 1/8″ wrap.
That allows for crooked or un-plumb corners, and lets you plumb up the next strip. It also allows a little “give” if the corner or drywall should move, and prevents the wallpaper from buckling or tearing in the corner.
But I was afraid that 1/8″ wouldn’t be wide enough to withstand movement, and we might end up with a gap in the corner.
So I wrapped the paper a little more, like 3/8″ around the corner. Here I’m placing the next strip so that it overlaps onto this wrapped 3/8″.
BTW, the gooky stuff at the bottom of the picture is the top of the shower tile, grout, and etc. It looks bad, but is actually nice and solid – and way above eye-level.
Done. No worries about gaps opening up.

Fun Kill Point With Schumacher Versailles

December 3, 2021
The kill point is your last corner in a room, where your last strip of wallpaper meets up with the first strip you hung hours ago. This virtually always results in a pattern mis-match, In the photo above, if I were to add the next strip of wallpaper to the right of the striped section, in the order it’s supposed to be hung, a mis-match would result when that design lands in the corner and bumps against the leaves and flowers to the right.
I thought I could make it look better. Instead of matching the pattern in proper sequence coming from the left, I decided to cut a fresh strip and match it with the strip on the right.
This gave me a perfect pattern match. But left me with a 1″ gap between the strips.
I could fill that gap in with a strip of plain blue paper, cut from scrap wallpaper in the trash pile. But this particular pattern didn’t have any areas with 1″ width of unprinted paper. So I used my straightedge and a razor blade and cut two 1/2″ wide strips of paper the height of this area over the door.
Here I have placed the first of these next to the strip on the right.
Here I have butted the second 1/2″ strip up against the first one, and am tucking it underneath the striped strip to its left. The vertical lines in the design will disguise any ridges caused by the overlap. Besides – who’s gonna notice this 9′ up, anyway?
Here it is, finished and smoothed into place. Note that these strips are still wet, and will be homogeneous in color once they all dry.
Here’s the finished corner. Remember – it still needs to dry. You can’t notice that there’s an inch of extra blue space in there.

Pink Horses for Baby Girl’s Nursery

September 8, 2021
The homeowners had this board-and-batten wainscoting added to one wall of the nursery. It compliments similar elements in other areas of the house.
Finished. The side walls are painted a very, very faint pink blush color – just enough to add warmth and unity to the room.
Horses! The mom-to-be had the manufacturer enlarge the scale of the figures, to better fit the size of the wall. That’s a nice service from Spoonflower.
This wallpaper is hung by overlapping about 1/2″ at the seams. This is not common, but there are several companies that work this way. I actually like it. It eliminates the chance of gapping at the seams as the paper dries and shrinks. And it distributes torque / tension on the wall cross that 1/2″, so less worry about a seam pulling up due to wall surface delamination.
This overlap does leave you with a bit of a visible ridge running the length of each seam. A little bit noticeable here, but less so on a busier pattern with less “blank” areas.
Spoonflower is a nice company. But I like ONLY their “Pre-Pasted Removable Smooth” option. I am not as fond of their “Pebble” – mainly because they can’t describe clearly what, exactly, it is. And definitely Do NOT get any peel & stick product, by this company or any other (see page to the right.)

This home is in a new subdivision in League City.

What’s Going On With The Pattern Match?!

July 25, 2021

Turning this corner and moving from right to left, the pattern matched perfectly at the top of the wall (not shown). But as we get to the lower foot and a half, the pattern match goes askew. Wassup?

What’s up is a combination of un-plumb walls and bowed walls. All of the corners in this powder room were off-plumb by at least 1/2″ falling from ceiling to floor.

First, know that you don’t wrap a full sheet of wallpaper around a corner. You wrap about 1/8″ around the corner, and then use a separate strip to start as you move out of the corner; in this case, moving right to left.

If corners are simply off-plumb, I can usually make the pattern match near-perfectly … although that will cause the pattern to track up or down along the ceiling line. It’s a trade-off, depending on which is more visually important; ceiling or corners / horizontals or verticals.

But in this case, the walls were not only off-plumb, but bowed as well. You can’t hang a straight strip of wallpaper against a bowed wall …. Something’s gonna either gap or overlap. Some patterns will let me futz around and pull some tricks, but this one was not forgiving.

My only option was to let a little bit of the pattern repeat itself at the bottom of this corner.

Luckily this is between the toilet and the wall, and not very noticeable. The busy pattern further disguises the minor mis-match.

Overlapping At The Seams

June 30, 2021

Re my previous post … the strips on this 6-panel mural are intended to be overlapped, by about a full inch.

There are advantages to this. Since wallpaper shrinks as it dries, it an result in gaps at the seams. Overlapping the seams prevents that.

Wallpaper that is drying and shrinking is also tugging at the wall behind it, which puts stress on the surface. If that surface is unstable, this tension could cause the layers inside the wall to give way and pull apart, resulting in open seams and a delaminated sub-surface. Overlapping the paper redistributes and minimizes the tension, and it also eliminates an open area where the two sides of the seam could pull away from the wall.

A disadvantage of the overlap method is that you can see the cut edge of the paper (see photo), and you also end up with a 1″ wide ridge running under the paper the full length of each seam. In this case, with such a busy pattern, you are not going to see that ridge.

Compensating Around A Window

June 29, 2021

Going around windows, especially wide windows, can be tricky. Wallpaper expands, it twists, the design can travel up or down from the ceiling line – and all this can go on independently of each other, with the sections over the windows moving out of whack at a different rate than the strips below the window.

The challenge then becomes, when the next full-length strip is hung, joining the strips over the window with those under the window … getting the pattern to line up and the strip to lie flat on the wall without torquing out of shape.

In this case, the pattern lined up pretty well. But strips under the window ended up being wider than those over the top. So there was a 1/2″ overlap, which would mess up the pattern match. This 1/2″ also caused the full-length strip to warp and develop a wrinkle.

This was an easy pattern and placement for dealing with such issues. All I had to do was cut along one of the palm tree stems, slide the strip up so the palm leaf pattern lined up, straighten out the full-length strip and work out the warp, and overlap that 1/2″.

All that sounds simple. But the truth is, I probably spent the better part of an hour getting it all to work out.

Getting a “Fat Cut” in Corners – Using a Euni Plate

May 7, 2021

You never wrap a strip of wallpaper around an inside corner.

Corners are neither straight nor true-to-plumb. So trying to wrap around a corner will result in a warped edge, and most likely a strip that is wonking off-plumb.

So you cut your strip of paper vertically in the corner, leaving a tiny bit wrapping onto the new wall. See second photo.

Your next strip of paper will overlap on top of this narrow wrap.

Splitting the strip and overlapping means that you will cover up and lose some of the wallpaper design. Hence, the less you wrap around the corner, the less of the design will be lost in the overlap.

The thickness of the rolled edge of this stainless steel plate / tool is just perfect as a trim guide! Trimming against the rolled edge will yield a 1/16″ – 1/8″ wrap around the corner. So, when you overlap your next piece (the strip you split in half vertically), you are only losing a fraction of the wallpaper design.

This tool has other uses as well – some are too complicated to get into here. But the thinner edge can be used as a trim guide for regular wallpaper work. It’s shorter than most trim guides, so it can be used in small areas. The rounded edges can be used to press paper into areas, or to crease paper before trimming – without leaving marks. And the angle has a purpose – again, too complicated for here. Plus, there are other plates with different angles available, each with different uses.

This ingenious gizmo was conceived by Eunice Bockstrom, a Canadian and fellow member of the Wallcovering Installers Association (WIA). Once or twice a year, she has a metal shop make a run of these metal plates. Eunice has also invented some other very helpful tools, and they also become available when the factory makes a run of them.

We call all of these Euni Tools. 🙂
