I am a huge fan of My Wonderful Walls and love watching their Facebook page to see photos that their customers post about how they have made over their kids rooms. Its pretty neat seeing parents, who say they have no artistic ability, redo their kids entire rooms and have them end up looking amazing! My Wonderful Walls if you don't remember my review is a company who sells not only wall decals, which I love, but they also well wall mural art kits. The short of it is to put up a sticker with a cut out, you paint inside it, peel it off and wam bam you have a dinosaur or a rocket or a dog :)
My Wonderful Walls has sort of an "ugly room" contest, officially called "Make My Walls Wonderful Photo Contest" going on right now. People submit their ugly room photos, people vote, and then get the chance to win any product from My Wonderful Walls. The contest will run untill the end of October so make sure you check it out, its easy to enter!
PS I hear they are getting a pirate set - I want one :)
