I went to FiberFest in Marin County yesterday. It's an annual conference of a group trying to develop sustainable fabric, fiber, clothing.
At the tiny seller's expo, I bought carded alpaca fleece and two kinds of yarn, and very much enjoyed my visits with each seller. The conference itself had sold out by the time I knew the dates, but I was able to briefly stand in the back of the conference hall and hear part of one presentation.
Last year, I think the conference included cotton and flax growers; this year, it seemed to be only about wool.
Here are two six-month-old sheep from a breed developed in France and now being bred (in a very complex process) in the U.S.: Ouessant sheep. For a little more about them, see http://capellagrazing.wordpress.com/.
