I love the idea of using wall decals. They offer fun, bold graphics without the commitment of paint. The decals are incredibly easy to put up (my kids even helped me) and when they tire of it, you can create an entirely new look. We used the retro Mario Bros and Invader decals from Blik in their "hideout" under the stairs. I am also seriously considering using Blik's pattern, "Rococo Pop"(shown above) for my guest bedroom.
