Yarns > Texas Dyers! > Blue Mule Fiber Blue Mule Fiber was born out of a love for raising goats and sheep, and learning to process the fiber that comes with them. They have a small herd of Alpaca, 2 Cashgora goats and a tiny flock of Icelandic sheep for wool and vineyard grazing. Their farm to market products are carefully hand-crafted, allowing you to create one-of-a-kind art pieces. Located in lovely historic Fayette County, Texas, Blue Mule Farm and Blue Mule Fiber is family owned and operated.
