In addition to the hand dyed wool roving, I have lots of dyed mohair this year...from goats. I found a reasonable source for young adult mohair, yearling, in combed top. It is sleek & shiny...like fine jewelry!
It is great to spin very fine for lace or for making boucle's. Spun thick, by itself, it will be heavy and probably last nearly forever. Mohair is strong. It is wonderful added to a batt of wool to increase the luster or used as a single ply with plies of different fiber.
