Possible answers: --These can be expensive especially if you need a dozen or so. Take a dowel cut into 24 inches or so, or a chopstick also works. for each pinwheel you need a square of colored paper about 6 to 8 inches will do. Cut each of the diagonal folds leaving an inch at the center uncut. Fold the paper tips along the cut lines so the meet (do this one by one) at the center and glue to hold at the center. Let the pinwheel dry well. Now take a push pin and push it through the center (front to back) and then push the pin into the dowel or chopstick. Now you have a pinwheel! Enjoy. --These can be expensive especially if you need a dozen or so.
