I think it's cool to have something to wear that you knitted or crocheted yourself, but I'm an odd size and I'm getting tired of scarves. Socks seemed a good idea, so I actually crocheted a pair a few years ago.
I was at a knitting and Stitching show one year at Ally Pally and found this really cool variegated sock yarn. I started to crochet socks with it and found that it was highly likely I wasn't going to have enough for a whole pair. Crochet takes up about three times more yarn than knitting does, so I decided to learn how to knit socks.
Knitting is a very slow process for me so this sock is taking ages to grow. Here's the last known photo of the sock. It's not much bigger now, but I have been spreading myself quite thin lately.
