De-gumming is a way of releasing the sticky substance that holds the strands of silk together to form the cocoon, so these are still roughly cocoon shaped but fluffy by comparison with their intact counterparts. This is a natural protein fiber from silk worms so you will need to extract the chrysalis remains that will be throughout the product. These de-gummed silk cocoons are perfect for dying, spinning, or manipulating into fun silk crafts of unlimited possibility! With a little stretching you can fluff up the de-gummed silk cocoons and freely spin into yarn! Leave some bunched up and get creative with art yarns. Manipulate into shapes for hand painting or crafting.
