Little Boy Room Makeover!

Just recently I became very excited about redecorating my son's room into a "big boy" room.  He has been growing so fast and is developing more and more into a little boy, so I decided his room should reflect this.  As much as I wanted to paint his room, I resisted the urge.  I have decided not to paint any of the rooms in this house (even though they are all white), since we are renting and I don't want to deal with the cost or the hassle of asking our landlord.  So, I had to figure out other ways to inject some color and fun into his room.
