From Lost Fables Wiki
Silk comes from the mundane silk worm, and is spun together in looms to create silken cloth, which is very smooth and comfortable.
Weaving silk, though it requires a certain technique, is not especially difficult.
Use and Effects
Silk has no special effects. It is frequently used for comfortable clothing and bedding, and is slightly more expensive than twine, which is the cheapest alternative.
There are no silk Artifacts on Anoma, perhaps you can change this.
