Answer:Most commonly, wool is obtained from sheep. Angora, goat, yak, llama, alpaca and even camels also provide us with some good quality of wool. These animals have a thick layer of hair in their bodies called fleece which is used to make wool fibre. The underfur of Kashmiri goats is used to make fine shawls called Pashmina shawls.
