The Bernina Patchwork foot #57 with guide 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 1/4 (6mm) or 1/8 (3mm) seam allowances.
Other precision sewing techniques requiring a perfectly straight seam also benefit from the use of the Bernina Patchwork foot #57 with guide. Here, the edge guide is placed directly against the fabric edge or seam line to yield straight spacing’s and lines when sewing.
