Presenting, Buffalo Gals Bison Merino. Earlier this year Clara Parkes wrote Yarn Profile in Knitter’s Review and the back story of this yarn is fascinating. Here is an animal who is native to the Americas, but unlike llama or alpaca, not a fiber that is commonly used. This yarn is a worsted weight blend of buffalo down and merino wool. The rich, jewel tones combine with the warmth, softness and loft to make this a truly unique yarn. To knit a pair of buffalo wrist warmers would be perfection.
