Keep an eye on trick-or-treaters with a googly-eyed wreath. To make it, pick up two to three bags of white Ping-Pong balls online or at a sports store. Use hot glue to attach them, in layers, to a foam wreath form with hot glue. Once all visible parts of the wreath form have been covered, attach small and large googly eyes. Tip: It's best to hang the wreath with a door hanger, rather than wrapping ribbon around, so the layers of Ping-Pong balls remain undisturbed.
