Vinyl peel-and-stick wallpaper adheres to any clean, smooth, dry surface. It's "like a stronger version of a Post-it note," says Patrick Walker, president of 4Walls, a wallpaper firm in Cleveland.
How to hang it: Start at the ceiling and work your way down. "Don't take the backing off all at once," says Robertson Hartnett, a cofounder of twenty2, a wallpaper firm in New York City. "Remove a foot at a time, adhere the top portion to the wall, and peel away the backing as you go so that it doesn't stick to the wall where you're not working." Smooth out bubbles with a wallpaper brush. To fix large bubbles, lift and reapply. These papers are sticky enough to withstand repeated positioning.
Keep in mind: Self-adhesives are reusable, so save the backing in case you need to store the paper for a future application.
