Yep. I made this sock. It’s made with Tofutsies sock yarn. Tofutsies is kind of unique because it’s made with fiber created with crab shells! Not all of it. A small percentage of it. There is also some fiber made from Soy. As well as some wool and cotton mixed in there, too. This pattern is the Madder Ribbed socks from Knitting Vintage Socks. If you are on Ravelry you can see the specs here.
I really should be raking those leaves instead of knitting, taking pictures, or blogging. sigh.
