These weavers are hard at work, demonstrating the ancient style of weaving and continuing to prepare weaving for sale. They work primarily with wool warps and alpaca wefts. The fiber of the baby alpaca and the vicuna camelids is particularly prized. Nearly all the alpaca, llama, and vicuna in Peru are domesticated. The vicuna are shorn only once every two years, and it takes four to five animals to produce a kilo of fiber.
