Cut a slit in one of the plates along the radius to the center. Measure the width of the wearer’s eyes. Overlap the slits about 2" and hold in place while you pencil in the eye holes to your desired width, positioning them so that they are centered above the seam that will be at the bottom. Let go of the overlapping seam so the plate is flat again and cut out the eyes with the craft knife. Overlap the slits again and glue closed.
Cut out two ears from the ribbed edge of the second plate, about 6" long and 1 ¾" at the widest point. Fold each ear in half (press them against a table edge to help get a sharp crease).
Cut out an oval, about ¾" x ½", from a scrap of the ribbed edge for a nose. Cut six skinny strips, about 3" long, for whiskers.
Paint the ears and the face mask pink and the nose and whiskers black; let dry.
Glue the ears behind the top of the mask, the whiskers to the center point, and the nose on top of them.
Glue the dowel onto the back of one side of the mask.
