Papering Around Wide Windows
Using a carpenter’s level aligned with a design element in strip 1, mark a horizontal line above and below the window. Hang strips according to this sequence: 2A, 2B, 3A, 3B, strip 4. If necessary, make adjustments in strip 4 to match the pattern.

Papering Around Outlets
Before papering around an outlet or switch, shut off the power to the circuit and remove the faceplate. Paper right over the box. Then, with a utility knife, make an X-shaped cut over the opening from corner to corner. Trim the excess along the edges and reinstall the faceplate.
Papering the Faceplate
Before reinstalling the faceplate, sand and prime it and cut a scrap of wallpaper the size of the faceplate plus a 1-inch border. Apply vinyl-to-vinyl adhesive to the front of the plate and back of the paper. Set the faceplate up to the wall, cover it with the scrap to match the pattern, and stick the paper to the plate. Set the plate face down on a table and then trim the excess to within 1/2 inch of the edges and cut off the corners. Wrap the paper around the plate, pressing the edges firmly to the back. Cut the plug openings with a utility knife and reinstall the faceplate.
