I took some advice from that thread, and my first project was a hat, just to get used to knitting. It’s all loops in loops, you’ll get it quickly. I think it’s good to do something else first because socks come in a pair and I don’t think my second would have come as close to matching my first if I had dove in with them to start.
I think the best advice I got was to look up continental style knitting, since it tensions the yarn in your left hand. I hold my yarn the same for crochet and knitting.
