I've just been turned onto wall decals and am having a ball. They don't look like stickers at all. My friend told me about wall decals and they're great. They actually have a matte finish so they look like they've been painted on the wall. I started with a small project and did a bathroom, and I'm so excited. This bathroom is now a classy room, believe it or not. And the steam doesn't seem to affect the decals. Next I'll tackle our 5 y/o's room.
They can be fun! You can have your own custom ones made at the vinyl sign shops like Fast Signs and even Kinko's near you. Other large output graphics places can output things too. They make electrostatic vinyls that you do not have to adhere to walls as well.
