Lots of Defects in Today’s Paper

September 24, 2021
There is a lot of “fuzzy stuff” along the edges of the seams.
But most concerning is that the seagulls do not match from one strip to the other.
This photo shows you why. Look at the gull next to my finger, and compare it with the gull by my pencil. The gull at the top of the roll is fatter – it has more white wing area. Obviously this run of wallpaper got trimmed “on the bias,” meaning that the rolls were not cut straight, but at a slight diagonal … sort of like a very long trapezoid. This results in the motifs being cut at an angle, with some wider than others. That means that the motifs are not going to match up perfectly at the seams.
In addition, one double roll bolt had abraded areas, as if something at the factory swept across the material and scraped off some of the ink. I cut off and discarded the worst of this. Luckily we had a little extra paper.
More fuzzy stuff. This shows on the surface. And it prevents the seams from meeting properly. I was able to remove some of it with a sanding block. But some of it remained, and affected the look of the finished job. Luckily, not extremely noticeable.

I’ve hung this paper before and not had these problems. I hope the issue is unique to this run, and subsequent runs will be back to being perfect.

I usually have the client order enough wallpaper that we can work around issues like this. Also, because of the layout of the room, and the fact that there is only one motif that has to be matched across a seam, and it’s relatively small, I’m going to be able to finish the room with it all looking O.K.

Serena & Lily “Feather” In Boy’s Bedroom

March 20, 2020


I like Serena & Lily papers, and their “Feather” is one of their most popular. Here it is in navy in the bedroom of a young boy in the Woodland Heights neighborhood of Houston.

The room presented some challenges, but the pattern was accommodating. It took a whole lot of time, but when I finished, it looked great.

The 4-square house was built about 1920. In the ensuing years, the house has shifted. Which is a nice way of saying that the floors and ceilings are not level, and the walls are not plumb.

I started to center the pattern on a plumb line between the two windows. But a plumb line is plumb, and the window moldings were not, so the wallpaper pattern would have started going crooked along the windows and ceilings. So instead of lining my first strip up against a plumb line, I carefully placed it to straddle an area equidistant between the two windows.

This took a lot of measuring, a lot of repositioning, and a lot of trips up and down the ladder. And, yes, I even had the strip in place, trimmed, and done – and then realized that it was a tad off. So I pulled it off the wall and moved it over by a scant 3/16 of an inch. The effort paid off, because, as you can see in the first photo, the design is perfectly centered between the two windows, from ceiling to floor.

The next full strip hung to the right of the window on the right (no photo). This wall was way off-plumb, and was shaped more like a trapezoid than a rectangle. My job was to keep the pattern looking straight along the window frame on its left, as well as straight along the door frame to its right.

The only way I could do this was to slice the strip apart vertically, cutting along the vertical “stripes” in the design. Then I aligned the pattern to the left and right moldings. In between, I overlapped the “stripes,” distributing the discrepancy in widths between the sections. In this way, I accommodated for more than an inch of difference in width between the top and bottom of the wall. This did create a slight vertical ridge under the stripes, but it was disguised by the stripes themselves. And a little difference in thickness of the wallpaper looks a whole lot better than a crooked pattern.

To the right of that was a wide closet door. I hung the three strips over the door, and the pattern was placed perfectly. Yet when I stepped back and looked at it, the design looked horribly crooked.

I finally figured out that the ceiling and door moldings were not perfectly perpendicular to each other. In fact, there was a full 3/4″ difference in height between the left and right side of the area. This trapezoid shape was causing the strips to look crooked, even if they were not.

Again, my solution was to cut the paper apart vertically along the “stripes,” and overlap as needed, to make my strips look plumb.

I employed this trick as needed in other areas of the room.

The design itself was very helpful. The vertical “stripes” were not straight, so nothing had to be exactly-dactly straight or plumb. And the “V”s at the top of the wall were also irregular, as were the positioning of the diagonal lines, so I had flexibility in how high or low to place my pattern.

Throwing another wrench into the works was the fact that we had two different runs to work with (do a Search here to learn about that), plus one double roll bolt that was defective and could not be used, which meant I had to figure out how to make 10 rolls cover 12 rolls’ worth of wall space.

Another obstacle was placing the wallpaper against the stained shiplap wall – without getting paste onto the rough, un-cleanable wood. And let’s not forget to mention the “industrial” metal pipe that hung 1/2″ from the wall I was papering.

I used two tricks for this. One was using my Boggess blue cut tape to protect the wooden wall. The other again involved using the trim-along-the-stripe-and-overlap-new-strip-as-needed technique. Too intricate to explain, especially without photos. But it was a good trick and the perfect solution to ending the paper at the wooden wall.

Sounds complicated. It WAS! It took me 10 hours (3+ hours per wall) to get these 10 single rolls up.

When all was said and done, though, the room looked fantastic. All ready for the young boy to move in!

Other parts of the room have a heavy “industrial modern” look – exposed pipe, weathered metal light fixtures, unpainted original shiplap wood. The interior designer is Stacie Cokinos of Cokinos Design.

Tricky Twisting To Make Wonky Walls Look Straight

May 30, 2019


The townhouse where I worked today (Timber Grove area of Houston) had walls that were more like trapezoids than rectangles. Trapezoidal walls make wallpaper run off-kilter. With this rigid geometric print, that meant that the pattern would either mis-match badly in the corners, or start tracking (going downhill) badly along the ceiling line.

So I did this little trick, to keep the pattern straight and nicely matched in the corners. You’re looking at the strips laid out on my table; sorry, no shots of the paper up on the wall. But the pics will give an idea of the process. And it turned out perfect.

I split the strip of wallpaper in two vertically, using a straightedge and a fresh razor blade to follow along the pattern. When applying the paper to the wall, I was able to slightly overlap the left side of the second strip on top of the previous strip, with less overlap at the top and more at the bottom. This enabled me to keep the same design element in the corner to the right (not shown), all the way from the ceiling to the floor. When the next strip went up, the design matched perfectly.

Since the width of the overlap wasn’t more than 3/8″, the black lines of the design disguised any ridges that might be created by the overlap.

Overlapping like this caused some of the vertical lines to be closer to each other than they were supposed to be. See second photo. But the eye notices this much less than if the pattern were very broken up in the corners, which would effect both the horizontal and vertical elements.
