Map Dresser - so fun, and maps are pretty inexpensive or something you already have! I can see this applied to a child's dresser or headboard or pictures on a wall.- would paint the dresser a dark color maybe red or blue for a more masculine room.
Alphacolor Soft Pastels: I love them--but I feel like most artists either love or hate them (Aimee Bishoff hates them). Start with a basic set and dump them in a bowl. I'm really in love with the interplay between the Earth Tones and the Fluorescents.
