The last strip of paper you put up on a wall should be made to turn any corner it encounters. Because perfectly straight walls and perfectly plumb corners are rare, never start or stop a strip of paper at or in a corner. If you do, there will be a noticeable gap in the seam, or the pattern will be out of alignment. Instead, plan to run the final strip of paper on the wall into or around the corner.
What you'll need:
- Wallpaper
- Measuring tape
- Scissors
- Paste
- Chalk or a pencil
- Utility knife
- Seam roller
Step 1: Measure distance
- On inside corners, measure the distance from the edge of the last strip of paper you put up to the corner of the room.
- Do this at the top as well as at the bottom of the strip.
- Take the wider of those two measurements and add half an inch.
- Cut the next strip of paper vertically to this measurement.
Step 2: Paste
Paste and hang this strip, butting it to the edge of the previous strip and running it into and out of the corner. Smooth it on both walls and trim at top and bottom as necessary.
- Establish a plumb line on the unpapered wall, at a distance one inch less than the roll's width away from the corner.
- Hang the next roll of wallpaper so it overlaps the inside corner again.
- Smooth both edges together and use a seam roller to flatten them to the wall.
- When you get to an outside corner, wrap the wall covering an inch or two around the bend. A wrap of much more than that may wrinkle or buckle when you try to smooth it out. Make sure the next strip overlaps by at least an inch.
