I've finally come to the conclusion that I'm not going to be able to knit socks on small needles with fingering weight yarn because of the degenerative osteoarthritis in my spine. The pain after a few rows is not worth it. I'm much more comfortable knitting on two circulars (size 3 and up) with worsted weight or sport weight yarn. I wear Birks anyway and boot socks will be fine, thank you.
I joined the Sensational Knitted Socks KAL this morning. I think I'll learn to dye that Knitpicks Bare worsted weight yarn and knit something from the book.
