This foot has a guide to the right. If you line up your fabric edge against this guide it will help you sew a perfect 1/4 inch seam or topstitching. The marking on the toe of the foot is there for keeping your perfect distance on a corner. Once the furthest line on the foot matches the edge of the fabric, leave the needle down, lift the foot, twist the fabric, then off you go again.
Universal Snap-on Feet will attach to low or high shank sewing machine adapters. If you aren’t sure if this will fit your machine, check out our sewing machine feet guide.
