We visited Aoni Textiles shop this morning. They specialize in bast fibers: linen, hemp, and ramie but here are examples of wild silk from India. Look for the stem in the photo where the silk worm attaches the cocoon to a branch. Those stems are what the skein of yarn is made of. The loose fibers come from the outside of the cocoon–not the good silk from unwinding the cocoon. We were told nothing is wasted: neither the stems or rough stuff on the outside of the cocoon; it all goes into making carpets. The cocoons were bigger than I’ve ever seen, maybe 1 1/2 inches long ( and beautiful).
