So pretty they'll make you dizzy, these patriotic whirligigs spin in the wind. They're tacked to clothespins so you can clip them to anything -- like a bicycle basket. Cut two 5-inch squares in different colors from patterned paper. Glue back-to-back; let dry. Draw diagonal lines from corner to corner. Make a 3-inch cut along each line. Fold every other point toward center; glue. Affix to clothespin with map tack.
This idea is from Martha's website.
