Starting with three felt sheets, cut four 1/4 inch strips of felt in each. You will have 12 strips of felt. Arrange according to color. Bring all strips into a bundle. Holding strips in both hands make a knot in the center being careful to include all strips in the knot. Don't pull tight while knotting. Then sliding your hands toward the center of the knotted area slowly tighten the knot until it is a hard ball. Trim ends.
