The fibers and colors are beautiful, however there were inconsistencies in thickness, with some stretches of up to worsted weight in this otherwise sock weight yarn. I don't know that the single ply of this yarn would stand up to much wear as actual socks, but it's soft enough to wear next to the skin in places like the neck and head.
These are amazing! They are so much easier to use than the "bump" cable needles. It actually hangs out of the way and the stitches don't slip off while you knit the back stitches. I even cabled while riding a packed bus to work this morning with no trouble!
I had been dreading making the commitment to buying these, but I'm glad I did. They are very light and smooth. The problems are that the cords hold the box shape and the yarn tends to have trouble moving around the hard corners, and it gets stuck going over the join, but it doesn't snag.
