Making a horse mask is a little different from most other mask crafts because the shape of a horse's head is so different from that of other animals. A horse has a very long and drooping head, which is sometimes hard to translate into a 2D shape. However, you can make a horse head mask from regular card stock paper. Use the length of the paper as the length for the horse's head to achieve a semirealistic horse mask.
Draw the outline of the horse's face vertically onto a piece of card stock using a pencil. Make the head about 10 inches long and 7 inches wide. Make the general shape of the horse mask into a modified oval. Make the top part of the oval, which forms the head, wider than the bottom part, which forms the nose. Draw a small chin, about 4 inches wide and 3 inches long under the nose. Draw two oval eyes about 4 inches down from the top of the head. Make the ovals about 3 inches wide and 2 inches tall. Draw the outline of a nose from the eyes down to the bottom of the nose. Add two 1-inch bumps on either side of the nose outline for nostrils.
Draw the outline of two ears, each about 4 inches long, onto the second piece of paper. Draw the outline of a small 3-by-3-inch-piece of mane fringe onto the paper.
Cut out all of the mask pieces using scissors. Cut out the holes for eyes. Use a hole punch to punch two holes in either side of the mask; string an elastic cord through both holes and tie in place so the child can wear the mask.
Glue the ears to the back of the top of the mask and the fringe to the forehead between the ears using a glue stick.
Colour or paint the mask as desired with watercolours, crayons, markers or any other materials. Wait for the mask to dry before wearing.
