Wall graphics and stick-on designs are still competing with wallpaper and paint for your attention. For kids' rooms, we found these cute wall "candy" stickers that can be displayed in any way imaginable, as well as moved around for a quick design change for the kid who cares. This kit comes with 80 differently colored and sized dots, which adhere to painted walls and can be moved and removed with zero damage.










These are nice, sure, but I much prefer the set that Think Geek has:

We have these in our daughters room. They wrap across two walls towards the door and spill into the hallway. Our daughter has started asking to move the dots. Great look and inexpensive.
