Our Quilting Clapper is made from 1.5" red oak which is heavy and durable for all your needs. The clapper is used to help flatten seams and creases by absorbing steam and heat. Hence, resulting in a crisp, professional-looking finish, on your most difficult fabrics. The rounded top edge allows for easy and comfortable grip. The clapper measures 10.375" long, x 2.375" wide on the top and 1.5" wide on the lower tapper.
