The sewing factory needs leather/wool/leather+wool (three models produce different clothes)

Leather can be used to build a hunter's hut in the forest to obtain venison and leather.

After the establishment of the forest farm, the forest farm will automatically cut down large trees and small trees and plant trees. Forests can provide habitat for hunters' huts, increase the number of prey, and increase the yield of herbs in collecting huts and pharmacies.
