Free motion sewing disk set
Abstract:
A set of sewing disks for controlling the movement of a piece of fabric over the free arm and under the needle of a sewing or quilting machine. Each disk is flat and has an oval or circular configuration and comprises three registered, stacked adhesively attached layers—a first contact layer made of open cell foam, a semi-rigid intermediate stiffener member, and a second contact layer made of closed cell foam. When each disk is placed over a piece of fabric with the lower contact layer is placed adjacent thereto, the individual's fingers are exposed at all times and placed over the opposite contact layer. The intermediate stiffener layer spreads and evenly dissipates the forces exerted by the fingers to the top contact layer to the lower contact layer. Because the finger tips are not in contact with the fabric, soiling of the fabric by the finger tips is prevented.
