Adds specific tanning reactions for each animal skin type. You can tan skin, tough skin, chitin, shell, scales or rigid scales, into an amount of leather based on the creatures size. Usually around 2-4 pieces, smaller creatures might give none, while massive monsters give dozens.
Normal leather can be used for suede(3) or vellum(3) from one piece. Suede is very thin leather, useless for combat, but good for backpacks, quivers and clothes. Vellum is used for the library system. Alternatives are papyrus (thatchery) or paper (screw press).
Birds leave feathers upon being butchered, which can be used to make quills for writing or feather mattresses for beds.
You can upgrade leather by boiling it in oil to harden it (Equivalent to copper armour), then add bonestuds to the hardened leather to make studded leather (Equivilent to Bronze armour), and then stitch several studded leather pieces together to create lamellar leather (Equivilent to iron armour). Each type will be a little tougher, with lamellar being the best. The oil has a 25% chance to be used up by this process. Studs can be made from bone, vermin or horn/hoof. The same upgrade system in a smaller form applies to shell, scale and chitin (Equivalent to bronze armour). Using 2 units of it you can combine it to one unit of the "rigid" version (Equivalent to iron armour).
The newest additions are the tanning of a stomach directly into a waterskin, the making of rope from guts/intestines and tanning a pelt into a fur. A fur is the very same as leather, but also protects from cold. Fur is needed for glacier embarks. If you don't want the fur, you can shave of the hairs to create a piece of leather and a unit of hair thread. Horns can be shaped into a small dagger, for earliest militias.
