Hideworking

lingHideworking is extremely important for better living, specially without much commerce. With leather and furs you can make clothes and |tying equipment. Clothes make winter much less harsh, even productive. Tying equipment is essential for a lot of things like drying meat (which makes it last a year) or build items (like skis or rafts).

Hideworking changes skins form animals so they can be used to make other items.

There are basicaly two things you can do to a skin besides letting it rot:

Tanning
Command in game: [Alt] + J, [T] Tan the skin

Tanning turns the sking to leather or fur, depending on the animal the skin comes from.

Sheep, ram, bear, bagger, glutton, beaver, (wild) reindeer, (artic) fox, elk, stag, wolf, lynx, polecat, weasel, pine-marten, hare, ermine and squirrel skins turn into fur.[1]

Pigs, dogs and cow skin becomes leather.

To tan you need bark or fat.

Curing
Command in game: [Alt] + J, [C] Cure the skin (for preservation)
