I’ve seen the “no foot - hoop” method of darning in several Singer User Manuals, and need to give that a try someday too. Have you tried it yet Jim? I’ll have to admit that I’m hung-up on the older hopping attachments for the moment. There was also a presser bar mounted hopping foot #121094 that seems more popular than the needle bar mounted one. Maybe the needle bar mounted one didn’t pan out too well? I can’t seem to find much information on the #86294 model. Maybe it’s kind of like the Singer Zigzag attachments....not too practical?
