Leather works is a workshop which produces leather items out of tanned hides made at the tanner's shop. These items include armor, backpacks, waterskins, quivers for military dwarves, and clothes and bags for civilian use. Leather armor is typically less protective than metal armor, but is lighter and thus better for initial armor wearing training or for squads that require speed over defensive ability.
Decorating finished goods with leather is also done at this workshop. However, crafts made from leather are made at the craftsdwarf's workshop.
UI You can create differently sized clothing or armor. To do so, first add appropriate jobs in the workshop as usual. Then, return to the job list, swipe on a job item, choose Details, and set a race the item will be for.
