Somehow, dummy me is having trouble posting this.
The real credit in the attached file is to Eric the Sock Master. He was nice enough to volunteer to knit socks from my attempts at spinning sock yarn. Although clearly the yarn needed to have been spun finer than it turned out, the socks are still just beautiful with the cabling, and there was yarn left over for a hat. I am very grateful to Eric for offering to do this, and he has inspired me.
The fiber content is Superwash (Rambouillet and Columbia mix) plied with a single of lamb Cheviot, acid fast dyes. Cheviot is both durable and low felting, and I do not think the omission of nylon will be an issue here. I like the subtle marled effect and do not consider it barber pole. I rarely make any attempt to keep a dye bath super even, because variation in color creates depth and interest to me, but others might want more uniformity.
I have learned a lot so far trying to deal with the issue of non-merino sock yarn. I spin to relax, and spinning finely is really not my favorite technique. Some fibers were easier than others to spin finely and yet maintain strength. Cheviot has so far been the winner, and it is an easy fleece to scour and card. It's very crimpy and bouncy. I clearly see, due to the time involved, why most people offer millspun hand-dyed sock yarn rather than handspun sock yarn. Lots of work! For my vote, BFL makes more sense in commercially available yarns for durabilty, especially when blended with nylon (which dyes readily).
Well, you knitters of socks have inspired me, so sometime this winter I am going to try it myself, already have the proposed fleece dyed and will save the spinning for one of those long winter days when one has the Zen thing going. Thanks Men Who Knit!! and a special round of applause for Eric.
