To make ears, fold a brown pipe cleaner to create a triangle with 3 1/2-inch sides, and a 2 1/2-inch base. Twist the ends of the pipe cleaner together to complete triangle. Fit the pipe cleaner triangle to the edges of the felt "inside" ear piece, and glue together. Glue the "outside" ear piece to the felt within the triangle. Bend the base of the triangle into a small arc to create the shape of an ear.
