How is silk comforter made?
The best silk comforters are filled with mulberry silk. Long silk filling is more expensive because they are directly produced from an oval-shape cocoon that is supposed to produce high quality silk fabric. The cocoon is first stretched into a large web, after that it is stretched to open even more into one layer for the filling of a silk-filled comforter. It takes many layers and many cocoons to make a thick enough batting.
