You apply the prepasted paper to your wall and when you want to take it down you simply grab the corners at the top of the strip and pull it down. The wall does not need to be repainted or anything. They also have wallpaper with different textures that is designed to be painted on. That way you can paint any color you want and when you move you just take down the wallpaper.

When I design window treatments for our NYC interior design clients, I like to address functional issues in a way that compliments the rest of the space.
