This clip-on gathering foot allows you to create gathers in fabric easily. It can be used on a single layer of fabric or simultaneously join a gathered fabric to another flat fabric. The Gathering Foot is most effective with softer, lightweight fabrics. With a single pass of the presser foot, you can gather fabric or create a ruffle quickly. This foot is suitable for light to medium weight fabrics and utilizes a straight stitch at a length of 3-6, providing more gathering as the stitch length increases. Simply attach the Gathering Foot and you're all set!
