Use this foot for perfect topstitching and edge stitching over seams and un-level areas. This foot is also helpful when quilting to topstitch along the edge of binding where areas may not be level. This foot is used for uniform and precise topstitching. This foot is called bi-level because the underside of the foot is designed to compensate for different thicknesses of fabric.
