7. Wool

Yeah, sheep are an obviously source of wool, but did you know that alpacas – which are becoming increasingly popular as pets – also provide top quality specimens of the material?

Alpaca fiber is a genuinely hot commodity now – and it’s used by garment makers to create all sorts of items from blankets to couture gowns.

Alpacas range in price from a few hundred dollars to a few thousand, but they yield between five and 13 pounds of fiber annually (depending on the size of the animal), which can result in a tasty income over the course of the animal’s life.
