Catch the wind in these colorful foam pinwheels -- the perfect craft project for a breezy summer day. Make It: Cut a circle from a colorful foam sheet and trim six slits towards the center of the circle. Fold from the outside of the circle in and secure with a touch of glue. To embellish, thread wire through a bright button and attach to the pinwheel. Gently push wire through the back of the pinwheel and wrap it around a dowel wrapped with ribbon.
