Tape the fabric along the top of the wall to hold it while you work. Spray the wall and back of the fabric with liquid starch, then carefully spread the fabric out, watching for bumps or wrinkles. Spray the top of the fabric, as well, to soak the fabric through. You'll want to work in sections to make sure the fabric lies flat before it dries. Use a rotary cutter to trim away the excess fabric along the ceiling and baseboards, and any that's covering the light switches and outlets.
When you want to remove it, just press a damp sponge on the fabric and it'll peel right off without leaving any residue. Throw the fabric in the washing machine so you can use it again in your next home. Learn more here.
