The Bernina Three-sole Walking Foot # 50V with Seam Guide Triple sole walking foot # 50V with seam guide is a wiz at working with challenging fabrics. Especially well suited to machine quilting and to sewing “sticky” materials, this foot also helps you match stripes and plaids by preventing the fabrics that are being stitched together from shifting. Walking foot # 50V features a standard sole, a special quilting sole, and a sole with a central guide for edgestitching and stitching in the ditch. In addition, its two seam guides help you sew accurately. The result: projects with consistent stitching and perfectly matched patterns.
