I was knitting this sock yesterday in between matches - youngest son was in a football tournament - so progress is going quite well.
One lady asked me if it was 'proper knitting'. I wasn't really sure if she was serious - 'er, no, I'm just pretending to twist wool round little pointy sticks to while away the hours' or if she really didn't have a clue. I explained that it was going to be a sock when it grew up and that I was using circular needles. She went on to say that she knits scarves, so she's obviously not new to the craft and has just never seen circulars.
Personally, I can't imagine life without them. (Quick survey here - dpn's, 2 circs or 1 circ for socks?)
Oh and by the way, Posh Yarn's Martha is now my absolute, total, 100% favourite sock yarn. I never want to use anything else - after I've used up my stash of other sock yarns that is.
