Mosaic Pumpkin: Cut up pieces of masking tape, stick them on your pumpkin, spray paint your pumpkin black. Let dry, then peel the masking tape off and you have a mosaic pumpkin! ~ Let the boys make their own designs- way better than carving!
Paint blocks of wood with glow in the dark paint, then have some fun with black paint for their faces. OR Paint the wood black and the faces with glow in the dark paint so the eyes and mouth "float in air".
