I had made a lot of progress with just a plain generic sock with a slight twist, and I decided to try a "Dutch heel". Then, I decided that I didn't like the fit. I liked the look of the Dutch heel, however, I didn't like the fit. Since I already have so much time vested in this yarn and socks, I've decided to frog the heel and stick with the more traditional round heel. I was out of the frog pond for a little while, but then I had to jump back in. I ain't easy being green.
