I love to take a picture of toe-up socks right after finishing the heel. They fold in half for their picture so very tidily!
I call this the “Baudelaire heel,” because the instructions are in Cookie A’s Baudelaire socks. I work the heel almost exactly as written, without adjusting the number of stitches for my gauge.
(The first time I used this heel, I spent ages running through all the various calculations. In the end I only adjusted it by 2 stitches. Totally not worth the effort of having done the math.)
I say “almost as written” because I don’t do the thing with picking up the wraps that’s specified in the pattern. I don’t actually understand what those instructions mean. Every time I read them, I cock my head to the side like a puzzled dog. Arrr?
Instead, I just pick up the wrap and knit it together with the stitch it was on. Seems to work fine.
