This presser foot is used for piecing together patchwork with a seam allowance of 1/4” (6.4mm) or 1/8” (3.2mm).

Always ensure needle is set to center straight stitch. Align the edge of the fabric with the outer presser foot guide for a seam allowance of 1/4” or with the inner presser foot guide for a seam allowance of 1/8”.

There are also marks at a 1/4” spacing at the front and back of the presser foot, allowing you to see the width of the seam allowance before and after the needle entry.
