Bernina Patchwork foot 37
Because it’s designed for straight-stitching, Patchwork foot #37 is ideal for sewing 1/4” or 1/8” (approx. 3 or 6 mm)
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.
