To make the Handprint and Footprint Ghosts: Paint entire hand white & press onto paper with fingers in a closed position. You may also paint a foot white & place onto the paper. Add eyes and mouth when dry by either painting or drawing it on or by using googly eyes.
To make the Hnadprint Monster Hand (or Witches Hand): Paint hand color of choice & press onto paper with fingers in an open position. When dry, draw on scary-looking, black fingernails and add a few black lines to give it depth.
