I worked on that operation one time at the factory ... doing the binding around terry cloth bathrobes.
I was never proficient at it - - not enough practice time ... I think that run was about ten days of work, and I got better, but I never really trusted that attachment to do what it said it was going to do.
Maybe sometimes, a human spends too much time thinking about something and not relaxing enough to let the machine do what the machine was designed to do? LOL It is those blamed control issues again!

Haha! I just googled 'binding foot' and am getting lots of websites for Chinese foot binding, which does NOT sound nice!

Will try again with the words 'for sewing machine' on the end!

Looks interesting...

I asked about one from my sewing store, and she said not worth the money, oh and that is for a brother machine.

Well, I went to the website, watched fifteen minutes of video or more, and I wouldn't spend a dime on that thing. Too much handling, messing, and just plain dinking around. Cut your bindings three inches wide, and a lot of the mystique and hassle disappears.
The tool I used at the factory was actually a piece of metal (can't remember the names, but it was like a jig) that screwed into the machine. The bathrobe was on the left, the binding came in from the right and both seams were sewn at the same time. Had I known as much about quilting then, as I do now, I would have had a blast with that jig!
If I think about it, I will look for the jig I mentioned and paste a link to it here.
But, no .. I wouldn't buy the tool that was on that video.

Yes, this sounds more promising, will look at video next.

I have the martelli binding foot package, and way too much of a learning curve for me!!!!!

This is what I was talking about. Attaches right to the machine. This particular one is for a Bernina.
Haven't tried it yet, but it looks like if you type in the words
quilt bias binding attachment
you will find similar attachment for a variety of machines

This lady has a number of entries about a binding foot ... I would think that if one machine company makes them, most of the others do also.
I bought an old singer in a cabinet from a thrift store ... it had every attachment ever made for that machine. It looks like numerous binding feet came with the machine, as well as a ruffler, and many other things.
You can find the foot you are looking for to help you apply binding in a single stitching.
Good luck!

I have a binding foot for my Viking Designer SE. It doesn't work for mitered corners. I don't use it much, because mostly what I work on is quilts with mitered corners. It is nice, however, for whipping up a bunch of baby bibs and potholders.
