Leather

Leather is obtained by killing cows, mooshrooms, horses, donkeys, mules, llamas, and hoglins, or by bartering with piglins. It can also be crafted from rabbit hide or found in village chests, bastions, and underwater ruins.

Four rabbit hides can be crafted into one leather.

Leather is primarily used to craft leather armor, books, item frames, and horse armor. It is essential for enchanting (bookshelves), storage (item frames), and early-game armor.
