Yes, went to SnB with sock yarn in hand and needing a set of 2.25mm or 2.50mm needles. All set to go. The latest 'Yarn' magazine (yes it's out, though Woolybutt seems to have a very early copy), has two sock patterns in them and I thought I would try one out. Sounds like a good plan.
Poor Lorraine at Woolybutt, she was so embarrassed, having neither set. I didn't want to substitute needles any further, so I found another sock yarn that required a different sized needle and purchased that. I am going to do more than one sock, aren't I. So now I have a ball of Opal in the colour Neon, and a ball of Tofutsies, which includes Chitin (Shrimp and Crabshell) in a more sedate colour.
I did have problems though with the other pattern in Yarn, when it started from the toes. Couldn't figure it out so that it looked neat. I think that is one for a quieter time and a bit of research. The instructions were a bit on the light side and apart from how to wrap the yarn around the needle, didn't really help the novice. I suspect that there is an explanation in another issue.
Further problems - the pattern I did choose uses a more elastic yarn than I have, so it will be interesting to see if they stay up and fit.
