If you want to set a spooky mood for your Halloween party, try turning down the lights and casting images of larger-than-life ghosts on your wall.
Cut a ghost shape out of the center of the construction paper sheet (download the template), then slip the sheet into the report cover.
Draw the ghost's eyes and mouth directly on the plastic. Now tape the side of the cover to the paint stirrer. In a dark room, hold the sheet in front of a lit flashlight, adjusting the distance between them as needed to project the ghostly image onto a bare wall.
