“Herds of the little ones for their wool”
Animals bred and kept for wool are sheared once or twice a year, depending on the weather and species-since llamas and alpacas are downright dangerous, compared with sheep and angora goats, I can only imagine what a bitch it would be to get a mammoth on that shearing table without getting kicked or charged...
That's why I suggested cloning the pygmy mammoths for the wool. If it turns out they are too ornery to flip over for a shearing I'm sure some kind of shearing stock could be designed for them.
A friend of mine weaves things from buffalo wool- the wool is not shorn from the animals, it is collected whent eh bison scratch their backs on barbed wire fences during the one time a year they shed their thick winter wool.
