Build a mold for the ghost body: Cut a wooden skewer into thirds and poke through the bottom of a paper plate as shown. Thread a styrofoam ball onto the middle skewer. Further secure skewers to plate with tape, if desired, so they stand upright.
Saturate cloth in fabric stiffener and drape over mold to cover completely. After cloth dries (up to 3 hours or overnight), carefully lift ghost off mold.
Using a permanent marker, draw facial features onto ghost figure. Accompany with a written name tag.
