I finished my first sock yarn. It is a three-ply fingering, made from "Spunky Eclectic's" April '09 club fiber, wool and 10% nylon. I hadn't spun nylon fiber before, but it went fine. The colorway, "Soul Windows," has the colors of eyes. It ended up seeming mostly blue, but I spun it quite thin, going for sock yarn.
The three-ply should make a nice "basic" sock for the Nov/Dec sock club. It will be a bit thicker than other sock yarns, I think. (Not as thin as some "fingering" weight, but not "sport," either.) It may be about like Fleece Artist Somoko, which I had to knit at 58 stitches for a sock instead of the normal 66.
I have over 1000 yards (from a "double dose," 8 oz of fiber), so it will either be more than one pair or perhaps a gift of handspun for another sock knitter.
