Here are some homemade ideas too!
- for wall decor, Michaels' has some 12x12 black frames. Just go to the scrapbook paper aisle, find your favorite paper (themed to go with room, ie: space, etc) and frame it! Way easy and very inexpensive!
- purchase chalk board paint and paint an old dresser for some fun furniture!
- affix glow in the dark stars to ceiling--
- use metallic silver fabric for throw pillows and big floor pillows
