ABSTRACT:
Overedge crochet stitching provides a whip stitch appearance on both sides of a fabric. Each stitch has (a) two contiguous legs of thread on the upper surface of the fabric, extending from a needle hole to the edge of the fabric; and (b) two contiguous legs of thread on the lower surface of the fabric, extending from the needle hole to the edge of the fabric. Both legs on the upper surface are bent to form a two strand bight at the edge of the fabric. Both legs on the lower surface extend first through the two strand bight of the preceding stitch and then to a one strand bight which loops around the two strand bight of the current stitch. The method and apparatus involve a threaded needle which carries the thread through the fabric, a hook which pulls thread to the fabric edge above and below the fabric, and a retractable spreader which supports a leg of thread which extends up from the needle hole to the preceding stitch. The hook simultaneously pulls the spreader-supported leg and the needle eye leg of thread to the fabric edge where they are pulled through a one strand bight which was pulled by the hook beneath the fabric during the preceding excursion of the needle.
