I was able to get a pair of socks from that yarn. Once I frogged the other sock I cast on for a smaller sock. I even used the correct sized needle for the yarn, imagine that!
I haven't cast on another pair of socks yet. In fact, I am doing a stitch sampler in the round and it resembles a legging for a very tall, thin person. This way I will have a visual record of stitches to use on socks.
