where does silk come from?

best answer
Where does Silk Come From- Basically the silk comes from silkworms. The larva is the source of the silk. From the glands silkworms produce the natural protein fiber that forms the cocoon. The fibers come off the cocoon. It takes 2000 to 3000 cocoons to make a pound of silk. It was discovered in Xia County China between 4000 and 3000 BC.
