Emily Ocker's Circular Cast On :: I first saw this mentioned in
Elizabeth Zimmerman's Knitter's Almanac. I took some pictures when I finally managed to figure it out and you can find them here.
I had another pair of socks that were just not working out, so I unravelled the yarn and prepared the yarn for reuse.
Not knitting, but web site design or "the things I've used to get me this far".
