Silk

 is a building material that may only be acquired from the Merchant. It's original singular purpose is the crafting of high-tier church furniture, a total of 12 pieces being necessary for all available bench slots.

With the implementation of DLC, silk is now necessary in a variety of limited applications, such as curtains for the Woodcutter. In addition, during Stranger Sins, Koukol will ask you to improve your tavern's tables.
