When we were little, one Christmas, my mom and sister and I all made these really neat paper stars, which we dipped in wax, to hang on the Christmas tree. We had them on our tree for years; she might even still put them up.
Anyway, I never knew what they were called, but on Dollar Store Crafts I came across a different version of them, and discovered they were German Stars. I found a great tutorial on them. This is a wonderful project to do with kids too. Paper folding is always fun!
