I made these socks using Regia Bamboo 1071 (45% bamboo, 40% superwash new wool, and 15% polyamide), which my Hot Socks swap pal Lee sent me. These were a really quick knit. I used a 3x1 rib, Sherman short-row heel, and regular decreased toe over 64 stitches on size 1 dpns.
Regia Bamboo is incredibly soft. It's fluffy and bouncy and has a little strand of something that looks like it's made of pearls. Trekking also has a new line of bamboo sock yarn, but it doesn't compare with the Regia in terms of softness.
The socks are resting on a new addition to, yes, my fabric stash. Leslie warned me that some day, I would find myself hunting down and hoarding fabric; behold, the prediction has come true. The Lone Knitter would like to try her hand at quilting this year.
