Patchwork foot with guide # 57 - for perfectly straight seams
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 1/4 (6mm) or 1/8 (3mm) seam allowances.
