I've been feeling really dumb as I try to figure out how to make the toe-up sock heel. I had started with this video reccomended by Wiksten but I just couldn't make it work. Then I tried this tutorial and that was a disaster - I ended up with double the stitches I should have! Then I realized I could use the short-row yarn-over method that I learned in Craftsy. And then I went back to the initial video. I took tons of notes (yes - I have started a knitting notebook).
I have done all this in tiny socks for Antea. The left sock heel in the picture was done using the no-wrap method and the right sock heel using the Carol Feller method.
