I'm in Oregon. And, Nikki is correct - you do not have to know how to spin to sell your fibers. I think many of the alpaca people around here send their fibers off for processing. A few sell fleeces for handspinners but they take great care to make certain that these fleeces are top quality and extra clean. One grower I talked with spent 10 hours on picking a fleece to be certain that it was clean. Lots of work, yes - but she could ask and get top dollar for that fiber.
I think the alpaca folks have a co-op of sorts - they send their fleeces in and get product back. I suspect that they may be paid something for the wool they send in and then pay something for the product they get back for resale but am not exactly certain how this works. I do know that the products I have seen for sale at alpaca shows are not, for the most part, products made by the individual growers. I've heard, but do not know for a fact, that the fleeces are sent to SA for processing into finished goods. Anyway, the products the growers are selling is very good quality and yes, I have bought some of these items in addition to some fleece
Nikki - I agree with you on the hypoallergenic thing. True wool allergies are fairly rare. It is much more likely that someone claiming a wool allergy is allergic to the chemicals and/or dyes used in the commercial wool industry.
