For my daughters room we bought light blue paint (it was oops paint, so it was cheap) and painted the walls blue. I am in the process of painting blades of grass around the room. I will paint flowers growing around the room too. THere are some giant wire and nylon butterflies hanging from the ceiling. (It is cute.)

I would like to think of something like this for my boy, but I cant paint very well. Does anyone have suggestions- or better yet photos?

He loves Cars, but I worry it will be out of "style" in a year. It is also expensive to buy too many accessories.

Any ideas are welcome. Thanks!
