Historical version 2 of Kake's Red Crochet Socks (view current version)
No idea what the yarn I used was - 100% cotton, I think. Had it for years. I used a 3.5mm crochet hook and made the socks ankle-height, then did one round of double crochet over a doubled length of shirring elastic, then a round of plain double crochet, then another elasticated round.
