I am totally in love with these 3D door stickers from Couture Deco. The material is described as 'trompe-l'oeil on opaque white fabric with satin finish.' The stickers are washable, fire and UV resistant, and highly durable. You can adjust them to fit with a scissors and they're applied with regular old wallpaper glue. My only problem with them is deciding which one to buy! See all the stickers ($279) available at Couture Deco. POST UPDATE: The retailer has LOWERED the price to $199!!!
