This foot is used to insert fine piping into projects giving a professional finish to dresses, jackets, bags, placemats, book covers and so much more! This foot can also be used to make your own piping, which is particularly useful for achieving a perfect fabric match or unique print piping. This can be created using a chain stitch or a three or four thread overlocking stitch. After inserting, the piping the cord can be removed from the piping to reveal a 3mm insertion of folded fabric.
