ABSTRACT:
A chain stitch insert receivable in the bobbin case of a sewing machine is formed with a topside ledge which captures and consumes thread as a hook point carries a loop of thread around the bobbin case. The ledge enables the formation of chain stitches without the need for a special eyelet on the machine.
