A hide or skin is an animal skin treated for human use. Common commercial hides include leather from cattle and other livestock animals, buckskin, alligator skin and snake skin. All are used for shoes, clothes and other fashion accessories. Leather is also used in upholstery, interior decorating, horse tack and harnesses. Such skins are sometimes still gathered from hunting and processed at a domestic or artisanal level but most leather making is now industrialized and large-scale. Various tannins are used for this purpose.
