Leatherworking

Leather crafting or simply Leathercraft is the practice of making leather into craft objects or works of art, using shaping techniques, coloring techniques or both.

Leather dyeing usually involves the use of spirit- or alcohol-based dyes where alcohol quickly gets absorbed into moistened leather, carrying the pigment deep into the surface. "Hi-liters" and "Antiquing" stains can be used to add more definition to patterns. These have pigments that will break away from the higher points of a tooled piece and so pooling in the background areas give nice contrasts. Leaving parts unstained also provides a type of contrast.

Alternatives to spirit stains might include a number of options. Shoe polish can be used to dye and preserve leather. Oils such as neatsfoot or linseed can be applied to preserve leather but darkens them. A wax paste more often than not serves as the final coat.

Sweat and grime will also stain and 'antique' leather over time. Gun holsters, saddlebags, wallets and canteens used by cowboys and buckaroos were rarely colored in the Old West. The red, brown, and black tones develop naturally through handling and as the oiled leathers absorb the rays of the desert sun.

Due to changing environmental laws, alcohol-based dyes are soon to be unavailable. There are currently water-based alternatives available, although they tend not to work as well.

Leather painting differs from leather dyeing in that paint remains only on the surface while dyes are absorbed into the leather. Due to this difference, leather painting techniques are generally not used on items that can or must bend nor on items that receive friction, such as belts and wallets because under these conditions, the paint is likely to crack and flake off. However, latex paints can be used to paint such flexible leather items. In the main though, a flat piece of leather, backed with a stiff board is ideal and common, though three-dimensional forms are possible so long as the painted surface remains secured.

Acrylic paint is a common medium, often painted on tooled leather pictures, backed with wood or cardboard, and then framed. Unlike photographs, leather paintings are displayed without a glass cover, to prevent mold.
