The large opening on the front of the foot gives you wide visibility in the needle area. Use for free-motion, outline quilting etc.
Please note: Although this foot is a screw-on fitting, it works perfectly on machines that take clip-on feet. Simply unscrew and remove the clip-on presser foot ankle and you can then attach the foot as shown in the picture.
Suitable only for machines that have the front loading bobbin system as shown here.
