Some goats produce special fibers or wools in their coats that can be spun to make yarn for knitting and crocheting clothing. Angora goats produce curly long wool called mohair. You can use a female or castrated male goat for a fiber goat project. However, you must keep their fleeces clean all winter and harvest their fleeces every year. A fiber goat project is perfect for someone who likes goats, wants to learn how to spin, and likes to knit or crochet.
