You need:
- green construction paper, 20 by 20 cm
- white tempera paint
- white pencil
- fine markers in white and black
- colored markers
Draw staves on the sheet using a white pencil. Make fingerprints for the snowmen: use the tip of your finger for the head, use your thumb for the body. Wait till the paint has dried. Use a black fine marker to draw brooms, branches=arms, stones=eyes+mouth. Draw the carrot = nose with orange marker and draw caps of hats on some of the snowmen.
Finally, draw the text of We wish you a merry Xmas (or another Christmas song) under the staves.
