This is a yarn company that I was introduced to and found their sari silk yarns to be the best I've come across and I'm passing my find on to you.
Here's a little bit about what Frabjous Fibers says about their company:
“frabjous” means joyful, excellent, fabulous—the good feelings your creative outlet should stir in you! We are a small business based in southern Vermont and run by husband and wife team: Konstantine and Stephanie Shiman. We offer exotic handspun yarns from women’s cooperatives, creative kits, patterns, handpainted top, felt needle cases, and paper goods.
We import most of our goods directly from Nepal, where we are working with others to create safe, reliable, well paying jobs for women. We donate a portion of our profits to educational programs in Nepal, and help to purchase necessary equipment for cooperatives.
