The “Impossible Girl” socks (Pattern by Madeline Gannon) were knit out of the Madelinetosh BFL (Blue faced Leicester) sock yarn. I did not realize until I finished that they are 100% wool without nylon. They may be a bit less sturdy, so I will use them for special instead of everyday. I really enjoyed working with this wool and like the depth of color. And next time I may reinforce the toe and heel with nylon – or maybe not. It is sock yarn and may wear very well.
