While sitting outside enjoying the cool mountain air this morning, I finished the ribbing and bindoff on the purplish socks. To recap: these are the Pacific Coast Toe-Up Socks knit with custom dyed Trekking yarn on size 1 needles. I knit them two-at-a-time Magic Loop style, knitting both socks on one long needle.
Jeny's Surprisingly Stretchy Bindoff . It is a bit fiddly but it sure does work. I'll use it again.
