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. TIP: a large sewing table or cabinet makes quilt piecing easier and promotes greater precision as it supports your patchwork better. Enjoy the ease of sewing afforded by Patchwork Foot #37 – your partner when it comes to patchwork and precision stitching techniques.
