 Fellmongery is one of the oldest professions in the world and since ancient times, humans have used the skins of animals to clothe themselves, and for making domestic articles.Today the term has become restricted to the person or the operator of the machinery which removes sheep's wool or the hair of other animals from hides in preparation for tanning.The process of fellmongering has to be done quickly after the animal is slaughtered to prevent the hides from decaying before tanning can begin.
