Earth Yarn - 90% bison 10% nylon

Made in the USA from de-haired ultra-soft bison down (and a little nylon for added durability). A very versatile midweight yarn; from scarves and shawls, to sweaters and socks, warm, durable, soft and all American! This is the yarn we knit all of our “Extreme Gear” gloves, scarves and hats from. Natural undyed buffalo brown, or carefully overdyed.

Solid knit pieces; gloves, hats, etc., machine washing is just fine, as is drying on low. It will not shrink, and it will help the yarn to bloom.  I wouldn't recommend machine washing lacework though.
