Oh, I should have added. There not hard to apply, just like leather. Cut a square of beaver tail and soak it in water to soften, wrap your riser in saran wrap to protect it, wrap the beaver tail on the riser and stretch to fit the curves, use a couple of spring clamps on the front to hold the beaver tail in place and set it aside to dry. Once dry, put some barge cement on the riser and the beaver tail, put the beaver tail on the riser, cut the front two flaps to meet in the middle with scissors, then punch some holes to sew it up. Take a razor blade and trim the top and bottom edge and your done.
