Old Style #35 Invisible Zipper Foot

The Old Style #35 Invisible Zipper Foot (part number 0308207000 or 0306537000) is a specialized, high-quality presser foot designed for older BERNINA sewing machines to install invisible zippers seamlessly. It is characterized by two diagonal grooves on the underside that hold the zipper coils in place as they feed through, allowing the needle to stitch extremely close to the coil for a professional, hidden finish.
