I'm looking forward to some answers to your same questions. In cleaning my closets, I came across all sorts of pendleton woolI bougth many years ago to make suits - former life when worked in a professional office - now I do not need suits and the wool feels so nice to the touch. The wool looks in good shape -I stored it with cedar blocks so I do not see any moth holes.
So if anyone can answer the original question, you will make two board members very happy. :D
