This foot was originally designed for mending or patching holes in fabrics using a technique of lowering the feed dogs and moving the fabric back-and-forth under the foot to create the mending stitches. The same technique is used for free-motion embroidery and quilting. The shape of the opening allows for either straight or zigzag stitches up to 5mm in width, and the vertical spring action holds the fabric down as the needle moves up, keeping the fabric from “flagging” or pulling up too far with the needle.
The embroidery/darning foot is suitable for most domestic low-shank machines. To attach the foot, unscrew the existing presser foot or snap-on bracket and replace it with the embroidery/darning foot, hooking the white lever over the needle retaining screw. It is the up and down action of the needle that allows the press-release function of the foot.
