At its most basic level, leather is a skin that has been preserved so it will never rot.
It is a biological material that has undergone a chemical transformation to make it permanent, durable, and flexible. Without this process, a raw hide would either become stiff and brittle like a board or decompose and rot away.
1. The Raw Material
Leather starts as a byproduct of the food industry. It is the hide of an animal—most commonly a cow, sheep, or goat. In its raw state, the skin is made of water, fats, and protein fibers (collagen).
2. The Process: Tanning
The magic of leather happens during Tanning. This is the process of replacing the water molecules in the skin with “tanning agents.”
Vegetable Tanning: Using natural tannins found in tree bark (like Oak or Mimosa). This is the traditional “Old World” method used for harness making because it creates a sturdy, long-lasting leather that “remembers” its shape.
Chrome Tanning: Using mineral salts. This is a modern, faster process that results in soft, colorful leathers used for jackets or upholstery.
3. Why is it special?
Leather is unique because of its fibrous structure. Unlike fabric, which is woven together, leather is a dense, three-dimensional web of collagen fibers.
Breathability: It has microscopic pores that allow air to pass through at very slow and controlled rate.
Strength: It is incredibly difficult to tear because the fibers are naturally intertwined.
Malleability: It can be molded when wet and will hold that shape once dry—a quality crucial for making comfortable harnesses and saddles.
4. The “Living” Material
Even after it is tanned, leather is often called a “living” material. It reacts to the environment. It absorbs oils from your hands, it stretches with use, and it develops a patina (a natural sheen and darkening) over time.
The Craftsman’s View:
The Ethics of the Material: A Craftsman’s Responsibility
To a leatherworker, leather isn’t just a fabric; it’s a piece of history. We are taking a natural byproduct and turning it into a tool that, if cared for, can last for generations. However, the source of that material matters as much as the craft itself.
A Commitment to Ethical Sourcing:
I feel it is important to note that I do not hunt. The leather I use is primarily a byproduct of other industries—ensuring that a resource which would otherwise be wasted is instead preserved and put to meaningful use.
The Australian Context:
In Australia, we face unique environmental challenges. Our feral animal populations must be managed carefully to protect our delicate ecosystems and native species. In these instances, I will use leather acquired through ethical, managed hunting practices.
By utilizing these skins, we honor the animal by ensuring nothing is discarded. We transform a necessary part of environmental stewardship into a durable, functional piece of art. This approach aligns with a deep respect for all animals—whether they are the prey animals we partner with or the ones we manage to keep our environment in balance.

Tanning can also be done with urine or brains. Fun fact – the brain of an animal is exactly the right size to tan it’s whole hide.

That is a fun fact! I have seen the process of using urine. I haven’t seen how it is done with the brain.
