I am getting ready to redecorate my 6 year old sons bedroom. His room has been Spongebob for 4 years and we're ready to give him a little bit more grown up room. I am looking for ideas on how to decorate it in Lego theme without it looking Preschool-ish. I don't want to paint it primary colors on each wall, I'm thinking more grown up than that, something that will last him 4 years or so. He's a mature 6 since his brother is almost 10. Any ideas? Does anyone have pictures that they can contribute? I will post pictures of the project in progress. First things first, prime the walls. Currently they are an aqua color with bubbles all over to simulate being in Bikini Bottom.
