Wall decals aren’t just for sports fans — they’re for design lovers, too. (And renters, because they aren’t permanent and don’t damage walls.) WALLTAT Wall Decals, for example, offers hundreds of images inspired by nature, pop art and vintage design. All you need is masking tape, a friend to help hold the decal in place, and the squeegee included with the product to apply directly to your wall. Presto, instant color!
