After just a few days work, I have successfully cast on two socks to be knitted at the same time (on 2 circular needles), increased for the toes, and knit a decent portion of the foot.
I am already so much happier with this method of knitting socks. It really is very simple, once you get your head around it. I’m really enjoying slipping the sock on after every couple of rows. The thought of getting to the end of the knit, and having two identical socks, is just wonderful. No more SSS for me!
