Patchwork foot with guide #57 differs from Patchwork foot #37 only in that it has a built-in seam guide along the right edge of the foot. It is, therefore, particularly suitable for patchwork projects with ¼” (6mm) or 1/8” (3mm) seam allowances.
Other precision sewing techniques requiring a perfectly straight seam also benefit from the use of Patchwork foot with guide #57. Here, the edge guide is placed directly against the fabric edge or seam line to yield straight spacings and lines when sewing.
