Really simple. I cut some strips of paper (one pair long, one pair short, and one strip even shorter) and had my beautiful daughter color on them with white crayon.
The shortest strip will be down the middle. Then you line the other strips up so that when you bend them, the shorter ones will be in the middle and the longer ones on the outside. Line them all up on the top and staple , then do the same on the bottom. Cut a small hole where you want to hang them from and thread some clear thread through them. I just used clear pushpins to hang them up and... VOILA! Super fast, easy, cheap kid decor!
