I purchased these Star Wars wall decals at +Amazon.com. The decals includes several figures of varying sizes, as well as symbols and ships. The decals stick right on walls or smooth surfaces; our walls have some texture but so far they have stayed on well.
These are a fun addition for notes and messages. I put some here on his book caddy, as well as on his front door and on the top of his dresser.
Although I looked into getting a Star Wars comforter and pillow set, they were expensive. I ended up going with a dark blue comforter. We also had a space themed pillow case that Nana made that fits the decor perfectly.
