How do you extract natural fibers from plants and animals?

Natural fibers can be extracted from plants and animals through various methods. For plant fibers, such as cotton or flax, the process typically involves harvesting the plant, followed by retting (soaking to loosen fibers), and then separating the fibers from the stalks. For animal fibers like wool or silk, the extraction involves shearing the animal or collecting the cocoons, followed by cleaning and carding to prepare the fibers for spinning. Each method requires careful handling to ensure the quality of the fibers is maintained.
