This is definitely the easiest one to make as long as you can find a big thick cardboard. If you have a big cardboard box, save it for this project. Cut it into the shape of a ghost. Support the cardboard figure with a strong stake. If you want to add the 3-D effect, use a beach ball for the head, paint it white and paint the face of the ghost the way you like. Cover the entire figure, head ball & cardboard with a big piece of cheese cloth fabric. Tie a robe around the ghost neck to keep the fabric attached to the cardboard. This flowing fabric will create an illusion of a ghost at night, in the wind, floating in the air. Chilling!
