This is Cormo, by Foxhill Farms in Massachusetts. AMAZING stuff.
I am a farm yarn freak. And I love natural colors. My friend Karen, who is quite the yarn connoiseur, turned me on to this yarn some years ago. I have been hoarding it ever since in my stash. This yarn is so soft, so squishy, so amazingly beautiful. It feels like the most resilient cotton. I cannot praise it highly enough.
When I Googled it, to come up with a link for you to read about it, I found that many bloggers have also sung it's praises. But the owner of Foxhill Fiber, Alice Fields, doesn't have a website. She sells her yarns at the New York Sheep and Wool Festival. So, next October, run, do not walk, to her stall and bury your hands in some of this amazing fiber.
