Add texture and surface detail to all types of fabrics by sewing on cord, wool and thick fabrics. This foot is uniquely designed to guide the strands being couched while making it easy to insert the strands into the foot. A swing-out spring blade is mounted on top of the grooves. Swing the blade open and you have free access to the grooves. Simply close the blade and you are ready to sew. A special slit on the side of the foot further facilitates the insertion of the strands. The three grooves in Foot #22 are larger (compared to Foot #25) to accommodate thicker threads, yarns or cords. For finer threads, yarns or cords, consider the use of Foot #25 (Cording Foot - 5 grooves).
