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.

Slip Paper Behind Molding

January 26, 2023
It’s so nice when the trim carpenter leaves a little space between the molding and the wall. Rather than spending 20 minutes trimming around these multiple angles and protrusions, I will be able to merely slip the wallpaper behind the corbel (decorative molding).
Added bonuses are that there will be no worries about edges of wallpaper curling up or away from the wall .
I also believe this teeny gap is beneficial to give some ease, in the very common event of the walls shifting and moldings stretching or shrinking. All due to humidity and temperature and rain fall … and settlement of the home’s foundation, and more.

More Peel & Stick Hate

January 17, 2023
so-called peel and stick wallpaper is not nearly what the vendors’ websites make it out to be. It is neither easy to install , nor easy to remove . Nor does it hold up very long. I won’t hang it, neither will most of my colleagues across the country. Even our British counterparts have asked us to not let it slip across the pond!
I won’t work with it, but one of the clients I visited yesterday did attempt to DIY try it on her own, with quite unsatisfactory results. She was kind enough to let me take photos .
Here you can easily see wrinkles next to the door molding .
gap at seam over door, warps along side door.
hard to see, but there are large wrinkles. Plus notice on the right, paper is not adhering to the wall.
seams shrink and gap.
P&S material is not even trying to adhere to the wall.

A lot of these failures are due to the homeowners’ lack of knowledge and experience with peel & stick , and with wallpaper in general. For instance, the textured walls should have been smoothed / skim-coated / skim-floated before applying the material . Wallpaper wants to adhere to a smooth surface – not to the “highs and lows” of a textured wall .
Next, most P&S instructions call for application on a semi-gloss paint , which needs to cure for 6-8 weeks.
Also, read the fine print, and you’ll learn that P&S is meant as a temporary wallpaper …. you can plan on it starting to fail in less than a year. That’s where you get the failure to stick to the wall , and shrinking at the seams . Of course, here you can see that that happened within a few weeks / days.
In this case, the material will be easily removable from the wall. But in most cases, if you’ve installed it on a smooth , primed wall, well, when stripped off, it will take the paint along with it. Leaving you with a nasty , pock-marked mess to have to repair. Click the link to my page on the right, about why to stay away from P&S.

Close – So Close! – Kill Point

January 10, 2023
The kill point is your last seam in a room, where your last strip of wallpaper meets up with the first strip you hung. Because that last strip won’t be its full width, this virtually always this results in a pattern mis-match. So usually this goes in an inconspicuous corner. But this room had none, and ending / killing in a corner would have left us with a 10′ high pattern mis-match.
So I opted to put it over the door, where the pattern mis-match would be only 18″ high – and where not many people spend much time looking up there, anyway.
Today I got pretty lucky, and ended up with almost a perfect match – within 3/4″.
But I had that gap to fill, and doing so would have ended up with the pattern repeating itself inside that 3/4″ gap. This really isn’t a biggie. The pattern is accommodating and, like I said, it’s up over the door.”
But I have fun with these kill points, and had plans for a better disguise. Usually a double cut / splice is used. You take a fresh strip of paper an overlap it on top of the one below, and then splice together. My first idea was to make a swerved D/C coming from the top down along the the left of the sign post, and then moving to the right of the BBQ truck, leaving enough white space on the top strip to cover the sign post and truck on the strip underneath.
But as I studied the pattern , I realized that if I moved my splice over to the right, I would avoid making curvy cuts and come straight down between the lake and the building. Finished: You don’t notice that there is an extra sunbather and that the building has an additional column.
There are some important precautions that need to be taken in doing these double cuts to avoid damage to the wall underneath,,,, but I didn’t take photos. But you can do a Search here to see previous posts with photos that chronicle the various steps. Like here:

Cool Trick Going Around Door

December 18, 2022

I’ve finished putting short strips of wallpaper over this wide entry way . My next strip will be a 9.5′ piece going down the left side of the door molding .
The piece above the door ended 1/4″ from the left edge of the door molding. Normally, I would butt my next strip up against the existing piece. Then, as I move down the wall smoothing the paper into place against the wall, there will be a 1/4″ bit of it that laps over against the full length of the molding. I would need to use a straightedge and blade to trim this off. And then use my damp microfiber rag to wipe paste off the molding.
This non-woven wallpaper is thick and stiff , and hard to press tightly against the molding, so a bit tricky to get a sharp , tight trim cut . And also difficult to ensure that exactly 1/4″ is being trimmed off . So it’s easy for the paper to go off-kilter , and for the pattern to not line up perfectly against the molding . Not a big deal on a busy floral pattern , but with a rigid geometric, it might be noticeable .
So I decided to try this. I wanted to pre-trim the strip to take away that 1/4″ . This would save me from having to do any pressing or trimming. And also ensure that the pattern would fall perfectly straight against the doorway molding.
I measured down 16″ (the height of the ” header ” over the doorway , plus a couple of inches for trimming at ceiling and then at the top of the door molding ) .
Then I used my straightedge , razor blade , and fine ruler (from Texas Art Supply ) to measure over 1/4″ and trim it off .
Don’t think this is a simple task … It’s hard to measure exactly the width of the bit above the molding that should be trimmed off. 1/4″? 3/8″? 5/16″?
Also take into consideration that most wallpapers expand when they get wet with paste . So that 1/4″ I cut off could extend to 5/16″ or even more. That would mean a gap along the door molding.
Next, if the strip above the door is not perfectly plumb , or if the door molding below it is not perfectly straight and plumb , the wallpaper won’t butt up properly against it, and may start to show a gap or an overlap.
Sometimes you can manipulate the strip of wallpaper so that it does butt up against the door frame. But that can result in warps and wrinkles , or a pattern mis-match of the next piece . Also, like I said, this particular non-woven product is thick and stiff, and not happy about being asked to twist into another shape. Pasting the paper – instead of pasting the wall – does help to make it more pliable , so you have a better chance of manipulating the paper as you want.
Here is the strip going into place. So far, it’s butting up nicely against the molding. And no need to trim anything or wipe paste off the woodwork – except for that little bit at the top, which was my ” extra ” allowed for trimming .
FYI, that dark stripe you see along the woodwork is a shadow.
Here is the wallpaper as it falls along the side of the molding. The pattern is lining up nice and straight and precise .
To be honest, at the lower 1/3 of the wall, the paper did start to torque out of shape , and wanted to leave a gap at the molding, which was trying to grow from 1/16″ to maybe 1/4.” Not a lot – but it sure would look bad to have a 1/4″ gap between the wallpaper and the woodwork.
Trying to “mush” it to the right to butt up against the woodwork was causing warps and wrinkles .
I was a little surprised, but the paste had caused the stiff material to become softened and pliable – just enough that I was able to gently work out all those warps and wrinkles , so the wallpaper laid nice and flat against the wall. AND the left edge didn’t become distorted, but fell nice and straight enough that the next strip was easily able to butt up against it nice and tightly.

Picasso Slept Here – Crazy Pattern in a Complicated Powder Room

November 11, 2022
This is a fairly large powder room with a sloped ceiling, as it is situated under the stairs. You can see a bit of the ceiling at the top of the photo. The room also had this odd recessed niche with “columns” on either side, and a door leading to a closet.
In addition, there were tons of the rounded / bull-nosed edges that have been common in new homes in the last 10 years or so. These are tricky to wrap wallpaper around, and equally difficult to trim wallpaper to the edge.
Here is the niche area done, with wallpaper wrapped around the columns, and cut neatly along the horizontal bull nosed edge above the entry.
Wrapping the wallpaper around this edge and onto the ceiling of the niche would have made the area way too busy and claustrophobic. Because these edges are never perfectly straight and level, it’s also quite likely that the wallpaper will go crooked, and you’ll end up with gaps or overlaps at the seams.
A better option is to paint that ceiling area. I suggested the murky green color that’s in the leaves on the wallpaper pattern.
Here’s the east wall of the room. The vanity and sink are at the bottom right.
Here it is finished. In this case, the fir-down underside was only about a foot deep, so less chance of the wallpaper going crooked, so I did wrap it around the rounded edge and underneath. Still, one of the wallpaper strips did twist askew, and there was a small gap at one seam. With this pattern, no biggie – I just cut out a leaf and pasted it over the gap.
I told you the room had crazy angles!
Note that in papering angled areas like this, you can match the pattern in some places, but there will be mis-matches in others, such as where the sloped ceiling meets the fir-down. This wild pattern is perfect for disguising any mis-matches!

Closer look at the lemons and leaves . And angles .
It looks like a Picasso painting, don’t you think? The homeowner wanted something wild and fun , to set off the white minimalism in the rest of the home .
The pattern is called Citrus and is by A Street Prints . It’s a nice non-woven material , doesn’t expand , and can be hung by the paste the wall method , although I opted to paste the paper , as I usually do.
Non-wovens are designed to strip off the wall easily and in one piece, with no / minimal damage to the wall when you redecorate . They’re usually a pleasure to install . They’re more stain resistant and more able to withstand humidity than many traditional wallpapers .

Stabilizing Section Over Door

November 8, 2022
I wanted to position this pattern so that the stripe ran right up along the right side of the door frame. That would be more visually pleasing than having half-sections of those angular motifs.
The stripe did run along the outer edge of the wallpaper strip, so I could have easily butted the edge along the door molding.
But that would have put a vertical seam running right up over the corner of the door. My experience has shown that this area gets a lot of stress, especially in the case of shifting foundations and walls. So I really avoid letting a seam fall there.
My solution was to take a strip and move the seam over – easy to do with this striped pattern.
We had very little paper for this job, so before cutting anything I made sure that reducing the width of this strip by one section of diagonal motifs would still allow me to reach the corner on the far right (not shown).
So I measured down a little more than the height of wall above the the door and kept that intact and full-width. The rest of the length of that strip I cut along the strip in the design, all the way down to the floor.
Here that strip is in place. Leaving the top portion a little long ensured that I had enough to cover this area, and then all I did was trim off the extra 1″ or so, just as you normally would trim around a door frame.
The best part is that we now have the paper reaching across that “danger zone” above the top right corner of the door, with no seam to split open or gap should the wall shift.
Here’s a close-up of the irregular strip as it falls alongside the door molding.
Here’s the left corner of that door. I did some tricks to get that strip straight along the edge of the door frame, too. No pics, but, in a nutshell, I cut vertically along the lines in the design over the door, to cut the sections apart. Then I overlapped the sections about 1/4″, with the vertical stripe disguising the overlap. This made each section of diagonal motifs narrower. Once I had narrowed the whole area by removing about an inch, I had pulled the full-height strip on the left over to the right far enough that the tan line lined up along the door frame, and above the door it butted up with the left edge of the last section of diagonal motifs.
Note that this is a very easy pattern to play tricks with, because, although there is a pattern match, it really doesn’t matter much if you ignore it. Also, the lines are not perfectly straight, but a bit squiggly, and that makes it much more forgiving.
In fact, because we were really short on paper, the only way to get the room done was to mis-match the design in most places. The homeowner was OK with that. In fact, she (and he) were delighted with how the room turned out.

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.

Narrower-ing A Strip For Better Seam Placement

October 11, 2022
Here I am moving from right to left across this wall, fixin’ to put wallpaper over, around, and then under this window .
The distance from the existing strip to the corner is 20.” The width of the wallpaper is 18.” This means that my next wallpaper strip is going to fall 2″ short of reaching that wall to the left. So another strip will be needed to cover that last 2.” That’s two full length, 9′ long strips to cover that small bit of wall space. And there will be a seam down the middle.
I’d like to use less paper and have less waste. And I sure would like to avoid having a seam down the middle. Both because installing it is a PITA and also because it would look better and be more stable without the seam.
If I could just make that next strip over the window narrower, it would pull the full-length strip a bit to the right, eliminating the second strip and the seam.
Each 18″ wide strip has two stripes of flowers running down it. There’s a little gap between these stripes, so it’s possible to split the strip in half vertically between the rows of flowers. Then I’ll have a 9″ wide strip filling the gap over the window, instead of an 18″ wide strip.
So here I’m using a straightedge and razor blade to split the strip. (Normally I do this on my table with my 76″ straightedge , but today I’m working on the floor and with different tools .)
Here is the piece viewed from the front. The pink bit of flower on the right side is going to match up with the corresponding flower on the existing strip over the window . I made sure that the left edge of this 9″ wide strip has no flowers or motifs crossing over the left edge. That way there is no pattern to match across the seam, so I can choose any piece I want for the final strip that will go in between the window and the corner.
Here it is in place. Now I have only 11″ of width to cover with wallpaper , and no seam down the middle .
Same procedure for under the window. Except I’m not trimming this piece to 9.” I’m leaving it about 2″ wider. One reason is because that full-height strip coming down between the window and the corner is likely to twist or stretch a bit, and thus won’t line up absolutely perfectly with the strip under the window. Having this strip under the window be wider will allow the strip coming down the side of the window, when it gets down to under the window, it will overlap the strip under the window by about 2.” So I’m going to double cut / splice these two pieces together.
I’m also not adhering this piece to the wall yet, because I don’t want the paste to start drying, as I will need wet paste and paper that is easy to pull off the wall, in order to do the double cut.
OK, so here we are over the window, getting ready to put in our long 11″ wide strip down alongside the window. Actually, I’m cutting this piece 12″ wide, to allow for trimming along that left edge in the corner. This will also accommodate if the paper twists or shifts over that 9′ drop from ceiling to floor.
I chose a flower to put at the top of the wall that is different from what’s on the existing strip, so there won’t be repetitive motifs. But the right edge of this strip of paper has a design part that is meant to match up with the corresponding flower on the left edge of the previous strip.
But we don’t have that corresponding flower, because I cut that strip down from 18″ wide to 9″ and thus lost the left edge of the paper, along with the corresponding flower.
I don’t want this half-motif to be hanging in the middle of nowhere. Even 9′ up above the window, it might catch your eye.
No problem. I took my straightedge and razor blade and trimmed off 1/2″, which got rid of that design element.
Note that I did this before I trimmed this long strip to 12.” If I had trimmed it off before, then this strip would have ended up 11.5″ wide instead of 12″ and might not have fit the space since wallpaper can twist and shift during that 9′ drop.
Sorry, no photo of that strip butting up to the piece over the window and then dropping down the space between the window and the corner.
So that strip is in place now, and here we are under the window, with that 9″ wide gap to fill.
So I take the strip I had set aside for under the window and position it next to the strip on the right. Remember that I cut this middle strip about 2″ wider, so it overlaps the strip on the left. I need this overlap to do the double cut / splice.
When splicing on the wall, it’s important not to let your blade score into the wall. If the wall surface becomes compromised, the torque created when the paste dries and the wallpaper shrinks a bit can tug at the wall and cause layers of paint or etc. to pull away from the wall, resulting in an open seam.
So I’m padding behind where my cut will be made with this strip of flexible Lexion plastic. It’s thin enough to not make much of a bump under the paper, but thick enough that you can’t cut through it with a razor blade.
If you’re interested in this cool stuff, email me and I’ll hook you up with the guy who sells it. wallpaperlady@att.net
There it is on the wall.
Now I put the two layers of paper over it . Note that this is a paste-the-wall wallcovering, so there is no paste on the strip on the right, so nothing to stain the paper below it. If this were a regular paste-the-paper material, you can use thin plastic strips (like painter’s plastic) to cover up that paste.
Trim guide in place, and I’m getting ready to make the cut with a new single edge razor blade. You have to press hard enough to get through both layers of paper in the first try, but not so hard as to cut into the wall.
I’ve plotted where my splice will go, to not cut through any flower motifs, and to be sure to cut off that little bit of flower you can see shadowing through from the wallpaper piece underneath – just to the left of the large flower.
Once the cut is done, I remove the excess paper on the left.
Then reach underneath and remove the excess paper from the bottom strip.
Another shot of pulling out that excess bottom paper. Next I removed the Lexion strip. I set those in a bucket of water to keep the paste wet until I can wash in the sink.
Bringing the two strips to meet up and then smoothing into place. No paste got on the surface, so no need to wipe the seam.
A double cut / splice makes the absolutely most perfect and invisible seam, because both pieces have been cut together and butt perfectly.
Here it is finished. Technically, due to slicing the strips in half vertically, the floral strip on the far left is about 1/2″ further away from the strip on the right than it “should” be. But – eh – who the heck is going to notice that?!
What’s important is that no flower motifs got cut in half, no identical flowers ended up next to each other, here’s no seam down the middle of that space, and only one 9′ high strip of wallpaper was required (instead of two).
Done. Oh my gosh – now I’ve got to do the same thing on the opposite side of the wall!!
The pattern is called Sweet Pea and is by Serena & Lily .

Preventing Primer From Showing at Molding Edges

July 31, 2022
In a recent post, I mentioned how when there’s a strong contrast between the color of the woodwork and the primer, you don’t want any primer peeking out between the wallpaper and the molding. So when rolling on the primer, I cut in with an angled trim brush along the molding. But I’ll pull back just a tad, leaving a 1/16″ or 1/8″ gap or so, so the white primer doesn’t actually touch the woodwork.
This prevents any of the primer from showing after the wallpaper goes up.
Wallpaper paste doesn’t adhere well to glossy paint as is used on moldings, but this teeny bit of of a gap won’t be enough to cause adhesion worries.
