Silk cloth is made from silk thread, which can be gathered from the webs of cave spiders and giant cave spiders, which is then woven into cloth at a loom. Webs are automatically collected by any worker who has the weaving labor activated and access to a loom, which automatically produces the work task "collect webs" and turns collected webs directly into silk - no stockpile is necessary for this collection. (See web for more info.) Automatic collection of webs can be disabled from the ptions menu - this is useful if the accessible webs are located in a dangerous area or if you want to temporarily free up your weavers for other tasks.
Silk cloth has exactly the same value as plant fiber cloth (34☼).
Giant cave spider silk is very expensive (see Item value), because it comes from such a high-value creature. It's rare because it only occurs in biomes where a lair can exist (mountains/volcanos). Getting your hands on it requires you to be either very careful or have a little talk with the owner. Caging a spider and occasionally releasing it in the same room as weak/disarmed creatures allows for a renewable source of silk.
