Because it’s designed for straight-stitching, Patchwork Foot #37 is ideal for sewing 1/4” or 1/8” (approx. 3 or 6 mm)
seam allowances. In addition, Patchwork Foot #37 features three evenly spaced markings (1/4” apart) on its side
that make the square insertion of pieces in patchworking easier. A narrow groove under the flat sole serves as a
thread channel for smoother piecing.
