This recently developed sole updates your older two sole walking foot to allow you to stitch in the ditch for invisible quilting and stitch along edges for perfect edgestitching. The guide in the center of the sole acts just like the guide on edgestitch presser foot #10, giving you a precise guide to follow at all times. You must have the two sole walking foot in order to use this sole. Fits both new and old style two sole walking feet.
This item is not manufactured by Bernina, but is the same high quality you expect.
