I have turned the heel and am now working on the gusset! wooohoo!
This sock is very addicting- the BEST part was the one I most worried about (turning the heel). Unfortunately, I happened to tell my mother that I was learning to knit socks and she just sounded very puzzled and asked why on earth I would want to knit socks. I tried explaining it but I don't think she understands it at all.
But it has been a personal goal of mine since I started knitting and I'm really enjoying watching the sock take shape.
