I didn't want to overwhelm the room with decor. I'm trying to keep them pretty simple because I think it's easier to keep looking clean. I found a cute green bedroom set at Target and used an old piece of a fence for a headboard.
I painted little trees on a canvas by taping off lines and then tracing the bottom of a glass for the blue circles. I put our little green chair thingy underneath it to give her somewhere to sit and do her homework.
For the curtain pulls, I bought some big antique looking doorknobs from Hobby Lobby and painted them white and then sanded the edges.
