Using a few materials and imagination, you can make a sheep mask for a costume or to play. Consider experimenting with colour to make a black sheep, black-faced white sheep or regular white sheep. When working with scissors and glue, young children should have adult supervision and a clean, well-lit surface to work.
Cut out a large oval on the cardstock. The sides of the oval should touch the sides of the paper.
Halfway down the oval, cut out two circles for eyes. One inch down from the eyes, in between them, draw an upside down triangle for the nose and a mouth beneath that.
Cut half circles using the corner remnants of the cardstock. Color them black. These are the ears. Staple ears to top of the head on either side, rounded part exposed.
Staple one end of the elastic band to the side of the face, just below the ears. Holding the mask in front of the wearer's face, pull the elastic band taut around the head and staple the other end to the other side of the face, just below the ears. Cut off excess.
Glue cotton balls over the surface of the face, covering every inch of the mask (but not the ears). Allow to dry.
