Red craft paper
Plain notecard or card stock
Cut Santa-hat shapes (minus the pom-poms and white trim) from the craft paper, then glue one onto each card. Glue a pair of googly eyes a fingertip's width below each hat.
Pour white tempera paint onto one paper plate, and a dollop each of red, black, and pink (mix some red and white) onto another. Stamp white handprint beards, then use fingertips to stamp the trim on the hats, and a nose, mouth, and cheeks on each face.
