Patchwork Foot #37D is expertly designed for straight-stitching, making it perfect for sewing 1/4” or 1/8” seam allowances (approximately 3 or 6 mm). This foot features three evenly spaced markings on its side, each 1/4” apart, which simplify the square insertion of pieces during patchworking. Additionally, the narrow groove under the flat sole acts as a thread channel, ensuring smoother piecing. For optimal results, consider using a large sewing table or cabinet, as it enhances precision by better supporting your patchwork. With Patchwork Foot #37D, you’ll experience ease and accuracy in all your patchwork and precision stitching projects.
