Grandkids are fascinated by pinwheels, and they'll be eager to learn how to make their own. Use these detailed instructions, or wing it, drawing upon your childhood memories. In order for your pinwheel to turn freely, the pinholes must not be too tight. Use a hole puncher to make them, or simply wiggle the pin to make the holes larger. Another hint to make your pinwheel more free-wheeling is to insert a bead between the paper wheel and the stick that forms the handle.
