Draw a Halloween character (bat, cat, pumpkin, ghost, etc.) on a piece of construction paper (just make sure the eyes are at least an inch around); cut it out, including the eyes. Trace the cutout onto another piece of paper and cut it out too, including the eyes. You now have the front and back. Glue tissue paper over the eyeholes on the backside of the front cut out. Glue the front and back together (make sure to line up the eyes) so the tissue paper is hidden inside.
