Every year, Agribition is held in Regina at the end of November. It's a large agricultural fair. This year, Buffalo Gold from Texas is one of the displays in the commercial exhibits. There is buffalo yarn, knit items, and fiber for sale. Buffalo Guy Ron (BuffaloGuy on Ravelry) is very nice and has a great sense of humor. I volunteered to take my Joy wheel and spin some of the buffalo fiber at the set up.
It's pretty amazing stuff. It's so soft and about six times warmer than wool. It wears very well and can go into the washer and dryer.
Here's the fiber:
I've been spinning very fine lace weight to make it last longer.
My sister Darcie is working there for the week and she has more pictures of the buffalo yarns on her blog.
