Quilting foot #29C is a special presser foot for easy free-motion, outline and stipple quilting. The vertical spring presses the foot securely to your project, preventing the fabric from riding up with the needle (flagging). The material therefore lies flat while it is being sewn, allowing you to produce neat, consistent stitches. For even greater sewing ease, Quilting foot #29C features a clear sole, affording you a perfect view of both needle and stitching area at all times.
