Looks nice, huh?But these rounded edges , especially arches , have been a thorn in the side of wallpaper installer s since they became popular more than 10 years ago. Hanging paper on them and trimming neatly at the right point is difficult. Because the paper is hanging over the edge blocking your view of where you need to trim . A level or laser level don’t always work because the home’s framing isn’t always perfectly plumb . Metal straightedges / trim guides are useful, but can slip and mess up your cut. The arches present their own challenges because a straight edge won’t line up with them . A colleague in the Wallcovering Installers Association ( WIA ) invented this gadget , which is a huge help. This is a 1.5″ section cut off from the 10′ length of bull nose corner bead used in the drywall construction of these edges. Then you cut notches in it at the point on the corner where you want to trim your wallpaper . Some installers place a trimmer blade in the notch and slide the gadget along the edge, trimming as they go. I find that the thing wobbles too much for an accurate trim, plus it’s difficult to hold the blade while you’re sliding the thing down the wall. So I put a pencil point into the notch and draw a line along where I want to trim. Then I can use a straightedge and trimming blade , or a scissors, to cut along the line. Makes a nice, even, straight cut! Note that I like to wrap it about 1/3 of the way around the rounded edge.OK, so you’ve seen how I trimmed along the edge to the right. Now here’s another trick that I’m going to use on the edge to the left, as seen in the photo. The wallpaper strip is 20.5″ wide. But I trimmed it vertically so that the piece over the arch is 10″ wide. That correlates to the point where I want to trim the strip that will land on the rounded edge going down the wall. Note that I have not completely trimmed the part under the arch on the left side, because I want to be sure the cut edge lines up with that on the next strip I’m going to hang. The blue plastic tape is there to keep paste off the wall paint . It will be removed after the piece is trimmed to fit. Now here I’ve placed the remaining 10.5″ wide left section of the strip of wallpaper. You can see how it’s falling perfectly along the bull-nosed edge – saving me from having to use a blade or straightedge or gadget. Note that this works only if the edge is perfectly plumb , and that the piece above the arch is also perfectly plumb, and my new strip is hanging perfectly plumb. This paper is a non-woven material, and is somewhat stiff and unbending , so not really amenable to twisting or tweaking into place. Plus, you want to keep that left edge straight, because your next / subsequent strip will need to butt up against it. Trust me, I did a lot of measuring and shooting the laser level before I pasted or hung any paper! Now that it’s in place, I can go back and trim that remaining bit under the arch, making sure that it meets up in the corner with the edge of this piece .Here’s another shot of it finished. Closer up.This tree branch foliage pattern is called Twining and is by Graham & Brown . I like most everything they make. The non-woven substrate is designed to strip off the wall easily and in one piece , with no damage to the wall , when it’s time to redecorate . This home is in the Oak Forest / Garden Oaks / Heights neigborhood of Houston .
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’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.

The homeowner very much loves this simple, tone-on-tone shore bird pattern for her dining room – just the top , above the chair rail / wainscoting. Here I’m plotting where to best situate the pattern on the wall , between the chair rail and ceiling , while keeping the most important pattern elements and motifs intact . (no cutting off birds’ heads at the ceiling , nor at the wainscoting ) I’m also checking the pattern match . It quickly became evident that the pattern match, as laid out by the factory, was incorrect . Match it at the bottom (by my thumb ), but as you move up , the pattern goes a little out of whack . This is actually not all that bad , and is considered acceptable – the industry standard allows for up to 1/8″ – 3/8″ mis-match . Hand-trim screen-print materials such as this are particularly notable for pattern mis-matches . For the record, they’re also known for curling edges , puckering , waffling , and other issues that make them difficult to hang , as well as questionability as to how long they’ll perform on your wall before wanting to resort to that curling at the seams . More pattern mis-matching . But the situation got worse . These high-end screen prints often come with an unprinted selvedge edge that has to be trimmed off by hand , with a straightedge (the blue metal thing ), a razor blade – and a steady hand. If the trim guide marks printed on the material by the company are ” off ,” then you’re supposed to ” trim to the pattern .” This means that you find the design element on the left edge of the paper and then find the corresponding element on the right side, and place your straightedge so that your trim cuts will result in the two edges matching up perfectly. (Or at least within that 1/8″ -3/8″) At this point, the white lines in the design – let’s call them ‘grapes’ – are abutting my blue straightedge , and should meet up perfectly with the corresponding white lines on the grapes on the opposite side of the subsequent strip of wallpaper. But, unfortunately, with this material, that didn’t work. If I lined my straightedge up with the pattern design elements , as in the photo above this one, by the time I moved down a few feet , as you can see in this photo , the pattern begins moving away from the straightedge . The white grape outlines do not butt up against my straightedge. The likely reason is that this material has been printed on the bias . That means that the artisan at the factory got his screens out of whompus , for lack of a better term. ” Trim to the pattern .” OK. So here I’m placing my straightedge at 1/8″ away from the ” hook ” in this design . Still the same distance from the “hook.” But the white lines are starting to move away from the straightedge. Here they’ve moved farther off. With this design, from a distance , you could maybe live with the white lines not meeting up perfectly. But what you couldn’t find acceptable is that the tan area between these white elements would be growing wider diagonally as you move both up and down the wall. Look at the photo. You can see the tan area growing larger . But it gets worse as it spreads farther … As that tan section grows wider like a “V” or a wedge as you move up or down the wall, it additionally pushes the design motifs at the top of the ceiling or at top of the wainscoting either up or down along the horizontal lines of the ceiling and wainscoting . So not only do you get a widening tan line between each seam , you also get the birds’ heads moving up or down from where they’re supposed to be positioned below the ceiling or above the wainscoting . I spent an hour and a half trying different placements and trimming methods . I knew the client loved this pattern and that she was willing to accept reasonable flaws in the pattern match and positioning. But even given that, I wanted her to have a good looking dining room – not one with uneven spacing between strips, or grossly irregular positioning along the horizontal lines in the room. I even consulted with several (five!) “high-end” installer buddies of mine. No one had a ” tip ” for making an improperly printed design fall correctly on the wall. In fact, all five of them said it couldn’t be done. I determined that this material was unhangable. As mentioned, I tried to find an installer buddy who could make this work and get this client’s dining room done in time for Thanksgiving dinner. But no one wanted to take it on. I don’t know if the manufacturer will replace the paper or refund the $ spend. Manufacturers are usually keen on saying that “it’s the installer’s fault .” I can say that I’ve had similar issues with Meg Braff papers in the past. The homeowner really loves this pattern. It’s possible – but not assured – that purchasing the same design but in a different run will yield a better factory printing job. Just a note that printing defects , curling seams , wrinkling / quilting , and more, are somewhat common with hand-screened wallpapers . And here’s another reason why I’m happiest when clients stick with middle-of-the-road, or slightly upper priced , wallpaper options . Email me and request my Info Pack (or see the link on the right) for more information and brand name recommendations. Sad to bow out and leave this client with an unpapered room, and no viable solution or direction . But better that than to take on something that I can’t assure will look good. I hope she tells me what she ends up doing and how all this turns out.
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. The view from below.I used a pencil to touch up the edges of the leaves, to make them look more rounded and natural.
Hanging wallpaper around windows is tough, because getting the pattern to match above the windows, and then down the side and then match up with the pattern under the window is really tricky.
ESPECIALLY in a room where the walls are out of plumb, and the ceiling is not level, and also considering that wallpaper naturally stretches and warps when it is wetted with paste, plus various other factors.
I was lucky that this was a non-woven material, which is “dimensionally stable” – meaning it (supposedly) won’t expand, nor twist or warp when it absorbs paste. So, theoretically, after papering over and then under the window, the final full-height strip along the right side should butt up with the strip above the window, and then the strip below the window. That, actually, did work out perfectly.
But I still had to deal with the potential for the pattern to track off kilter, due to all those un-plumb and un-level factors. If it got off a little, I could tweak it a bit by pulling the last strip either higher or lower – the pattern is forgiving, and you would not notice a small pattern mis-match – especially 11′ up and behind drapes.
But I wanted to minimize a potential pattern mis-match as much as possible.
I figured that if the pattern stayed straight across the top of the windows, and also stayed straight across the area below the windows, it would have to match up with the final 11′ strip to the right of the windows.
To keep the pattern straight and at the right height on the wall, I used a level and pencil to draw a horizontal line that corresponded to the top of a leaf motif in the pattern. I did this both above and below the window.
Then, while hanging the paper, I made sure to keep that particular leaf at the same height of the line I had drawn on the wall.
It was a bit trickier than that, because it was a drop match, which means that that leaf only showed up on every other strip. But it all worked out.
One trick is to keep the strip “open,” which means that you put it into position, but don’t trim at top or bottom until you get the following strip into place. That way, you have the option of moving the previous strip either up or down to match the pattern, or, in the event that it won’t match perfectly, you can split the difference and spread the pattern mis-match between the two strips.
But I didn’t have to do much splittin’. By keeping the leaf at the height of my pencil line, by the time that last strip fell into place, the design matched up perfectly both above and below the window.
It’s been a month of “lines” type patterns, for me and for a number of paperhanger buddies around the country. The one I hung today on a headboard wall in an updated master bedroom in West University (Houston) is by Serena & Lily and is called “Etch.” It’s easy to see why!
Because the paper is dark, almost black, and because wallpaper often shrinks when it dries, leaving hair’s-breadth gaps at the seams that can reveal the white wall beneath it, I plotted where the seams would fall and then striped black paint under them, to prevent white wall from peeping out. The manufacturer helped, too, as you see in the fourth photo, where they have used a dark stock to print on, because a white backing might have shown at the seams.
Working your way around windows is always tricky with wallpaper, because the wet / pasted material stretches and expands and warps and twists, and that means that the piece you bring around and along side and finally down under the window might not butt up perfectly with the piece already under the window, and the pattern match might be off, too.
And that’s exactly what happened here… Although the wallpaper worked around the window on the right with no problems, on the window to the left (not shown), the wallpaper had twisted enough that it didn’t want to butt up against the strip under the window, the pattern didn’t match, and there was a large diagonal wrinkle running from the corner of the window to the left edge of the wallpaper. I don’t have a photo of it, but it was there.
This was an easy pattern to deal with that, though. What I did was, I cut along the bottom edge of one part of the pattern (see photo), pulled that strip up and smoothed out any wrinkles on the wall, then replaced it onto the wall, allowing it to overlap the bottom segment of that strip that was still clinging to the wall (see photo). Voilà! There is no wrinkle or twisted paper on the wall, everything is nice and flat and tight, and you absolutely cannot detect that the pattern is a wee bit off.
And, last photo, the entire day’s trash, all rolled up into one neat package, all ready for the recycling bin.
