In addition to our fiber shop is our custom fiber processing mill, which opened February 1st, 1999. We will process your fiber into batts, roving or yarn. I have been working with fiber and fiber animals for 30 years. I am a shepherd, spinner, and fiber artist. In addition to processing, I am offering roving, batts, felt , yarn and finished items processed from my own spinners flock of eight breeds of sheep as well as quality fiber we buy.
