Processing a hide is the process of tanning animal hides to make them into leather. Tanning is a process that uses chemicals to preserve the hide and make it more durable. The process involves soaking the hide in a solution of water and chemicals, then drying it and stretching it to make it more pliable. The hide is then treated with oils and waxes to make it waterproof and to give it a finished look. The end result is a strong, durable leather product that can be used for a variety of purposes.
