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 piecesin patchworking easier. A narrow groove under the flat sole serves as a thread channel
for smoother piecing.
