Work with hides involves the process of tanning, which is the process of treating animal skins and hides to produce leather. Tanning is an ancient practice that has been used for centuries to preserve animal hides and make them suitable for use in clothing, furniture, and other items. The process involves soaking the hides in a solution of water and chemicals, then drying and stretching them. The result is a durable, flexible material that can be used for a variety of purposes.
