This is a very cool star and frisbee that transforms. (This is not my work but I just want to make everybody know about it. The first pic is the star and second frisbee.
Step 1: Folding
Either buy origami paper, you can get it at Michaels, or cut eight pieces of square paper, any size. I didn't have any more origami paper, so I unfolded my star, so the folds are already made. Use the video if I didn't explain good enough for you.
1. Fold the top edge of the square paper down towards you. The open ends should be facing you.
