Has anyone used this specific foot? There is a clip to attach it to the presser-foot bar and the hook, seen in the photo here, that clips to the needle screw. Is that it? Nowhere do I see a screw to secure it to the presser-foot bar. It seems unstable. Could you please confirm the method of attachment? Thanks!
