Anyone use Elizabeth Zimmermann's M1?

It says it’s a backward e wrap. Is this like a yo? Please help! I am looking at the picture on Knitty and for some dumb reason, it’s just not clicking. Thanks in advance!

I don’t usually use that one. Here’s a link to the KH video. It’s the first one I think.

When I was at a sock class, the teacher did something very similar when I needed an extra stitch. It’s kind of like a yo I think, but it goes all the way around the needle instead of just over it.

Hope that makes sense!

Have you checked M1 Away on this site? Amy describes it fairly well IMO.

I also found this description.

No, I hadn’t seen it until you pointed it out… that’s it exactly! Thanks!
