  • Patent number: 6154991
    Abstract: A fabric workpiece holder is described for holding workpieces for various craft activities such as quilting and embroidery. The workpiece holder consists of a rigid hoop having a circumferential groove on its outer surface, an elastic cord that wraps around the fabric workpiece after it has been draped over the rigid hoop, and engages the circumferential groove on the hoop, and a novel clamp that allows the user to securely tighten the elastic cord, and maintain the tension therein, holding the fabric workpiece to the hoop. A unique feature of the clasp is an indexing ridge on the back surface that engages the groove on the hoop through the fabric. The ends of the elastic cord slide into holes on either side of the clasp and when the cord is tightened the clasp, including the ridge, are pulled toward the hoop.
