Transition New Wallpaper
Q: How should I transition new wallpaper around an arched doorway?
A: Since the wallpaper won’t fold neatly around a curve, and it can be tricky to cut an arch out of the paper during installation, the easiest method is to wallpaper the inside of the arch separately. First, apply wallpaper to the archway wall as your would any other wall. If wallpapering the adjacent room, do the same to the opposite wall. Smooth the paper and use scissors to trim the paper in the shape of the arch, leaving a 1-inch strip of excess wallpaper around the opening. Do the same to the opposite side, if applicable. Along the perimeter of the arch, cut the excess wallpaper into a strip of tabs. Cut closely to the wall’s edge and keep the tabs roughly two inches wide. Fold the tabs inside the archway and glue flat to the drywall. Then measure the width of the archway, cut a wallpaper strip to match, and adhere the strip over the tabs in the archway and flush with the edges of the wall.
