This presser foot features a small blade that protrudes below the flat surface of the foot. Use this foot for the popular stitch-in-the-ditch technique to sew directly through an existing seamline, such as securing a quilt sandwich or to secure facing to a waistband seam of skirts and trousers. Alternatively, use this foot to join two pieces of fabric with a zig-zag stitch, or to create perfectly straight top-stitching. Fits any low-shank machine that uses universal snap-on presser feet, e.g. Singer, Brother, Janome, and many others.
