Stir-Crazy

I think I'm going stir crazy! I love staying at home with Rylen but with the weather not being so nice its been hard for us to get out and do things. As I put Rylen down for his nap and rock him to sleep I stare at his blank bedroom walls. I have so many ideas to redo his room but I don't know where to start. We are planning on buying him some new big boy furniture sometime this summer which means we will have to buy some new bedding. Do I wait until then to paint?
I have also been trying to find some modern funky kids bedding online but everything seems to be trucks, sports or characters like Disney which we dont want. I know I need to get a plan of action started and written down before I jump into anything but I can be such an impatient person!
