These only take a little bit of sock yarn. I cast 40 stitches onto size 2 dpn's and knit in k2p2 rib. And then did a 3-needle bind-off when they were about 1/2 inch longer then the MP3.
These are the socks I've been knitting on sporadically: a plain sock with a slip stitch heel and a feather and fan sock with a plain heel. What I really want to do is cast on and knit two socks AT THE SAME TIME...one inside the other. I had heard about this several years ago and found an online tutorial, but never tried it. Now it's in the Jan/Feb issue of Piecework.
Instead, I cast on another scarf. I've always loved the twisted rib stitch on that gray sweater I knit for Middle a few years ago. So deceptively simple!
