One of the most versatile feet made by BERNINA, #10 is use by many on every sewing project. This foot is designed to allow perfectly placed stitches along edges and seams. Use it for any form of stitching where a straight guide is required. Edge stitching with all needle positions edge stitching on hems tucks fine edging (with or without cord) decorative edges sewing on lace and ribbon stitching-in-the-ditch The guide (blade) in the front of the foot serves as a reference when stitching along an edge. The guide on Foot #10 is shorter than that of Blindhem Foot #5, allowing greater maneuverability when stitching curved edges and providing more stability on lightweight fabrics Owners of 9mm rotary models 1630 and 180 should consider using Foot #10C (9mm), which will better match the wider feed dog on these models.
