I had never spun bison before and finally got the chance. I bought 9oz of blended bison and kid mohair from a lady who owns a spinning shop in Tonasket, Washington. She had pick up the fiber from a local bison. She had decided to card it with her neighbor's kid mohair.
Sadly, I couldn't make a nice yarn. From the bottom up: the fiber as I bought it, spun straight from the batt, hand carded and pick, hand carded and pick out as much VM and little lumps of bison as possible.
The best I could do was to pick it really well and blend it with alpaca. This one is alpaca, bison, and kid mohair in equal parts. Still the lumpy bison fluff makes the yarn look scrappy so I'm not going to spin rest. Lesson learned.
