A needing changed blue is so split for a desired output, garment upholstery, shoe upper etc, followed by dyeing (to give color), fatliquoring (to add fat/oil) & retanning (to fill higher the pulp structure) around needing changed affliction.

A leathers come dried & mechanically softened & brace oneself for finishing. Finishing is commonly handle coating a surface using paint-such as mixes. Suedes, Nubucks, etc. come finished by raising a nap of the leather by rubbing by owning emery paper (sandpaper).

A second run, that was utilized by Native Americans, involves "tanning" the skin utilizing brains. Number 1, the hide may be strung inside a frame. 2nd, a flesh from either skins is scraped when prior to. So a hide is allowed to dry when which a hair in these skins is shaved remove.
