The work has a definite wrong side:
After a couple of hours of footling, I reckoned I was ready to tackle the socks. First I followed Melody's link to remind myself how to do a provisional cast on. Aha, no wonder my crochet chain cast on didn't upzip, I was picking up through the wrong loop. Got it. I've made some progress on the socks:
And the other side:
It boggles the mind a little, but it's not really difficult. I'm using 4-ply cotton yarn. My yarn stash is at an almost-40-year low, but luckily the cotton yarn will work, though the socks may not be as stretchy as socks knitted in wool.
