Leather dyeing usually involves the use of spirit or alcohol based [[dye]]s 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.  The predominant brand of leather dye is Fiebing Leather Dye.
 
  
Alternatives to spirit stains might include a number of options.  [[Shoe polish]] could be used to dye and preserve leather.  Oils, [[Neatsfoot oil|neatsfoot]] or [[Linseed oil|linseed]], can be applied to preserve leather but darkens them.  For that reason, a wax paste more often than not serves as the final coat.
 
  
One interesting note, old gun rigs, saddlebags, wallets and cantanas used by cowboys and buccaroos were rarely colored in the old west.  The red, brown, and black tones develop naturally as the oiled leathers absorb the rays of the desert sun.

The only type of leather suitable for carving is vegetable tanned, top grain leather.  This is because the vegetable tanning process allows the leather to absorb water, which is used to soften the leather before the carving process, and the grain of the leather is necessary to allow the leather to hold the shape after the carving process is complete.  Other leathers lack these two essential qualities.
  
==Leather painting==
 
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 can not be used on items that can or must bend nor on items that receive friction.  Belts and wallets are not suitable for treatment.
 
  
A two dimensional surface backed with a board is ideal and common.  Often [[acrylic paint]]s are used on [[tooled]] leather pictures, backed with wood or cardboard, and then framed.  The glass in not put on top of such pictures because it causes the leather to mold.

Commercial stamps are available in various designs, typically geometric or representative of [[animals]]. Most stamping is performed on tree-bark tanned leather that has been dampened with water, as the water makes the leather softer and able to be compressed by the design being pressed or stamped into it. After the leather has been stamped, the design stays on the leather as it dries out, but it can fade if the leather becomes wet and is flexed.  To make the impressions last longer, the leather is conditioned with [[oils]] and [[fats]] to make it water-proof and prevent the fibers from deforming.

Leather carving is the process of giving a three-dimensional appearance to leather by a process of cutting and stamping the surface.


Raw Materials

The only type of leather suitable for carving is vegetable tanned, top grain leather. This is because the vegetable tanning process allows the leather to absorb water, which is used to soften the leather before the carving process, and the grain of the leather is necessary to allow the leather to hold the shape after the carving process is complete. Other leathers lack these two essential qualities.


Tools

Leather carving is accomplished using three main tools:

  • Swivel Knife
  • Rawhide Mallet
  • Stamp Set


Preparation

Before carving can commence, the leather must be prepared to accept the tooling by 'casing' it. This is done by applying water to the grain side of the leather with a sponge. After a short time, the surface of the leather will darken and feel cool to the touch. At this point, the leather is ready for carving. For some large projects, it may be necessary to re-case the leather as it dries during the carving session.


Swivel Knife Cuts

When the leather has been properly cased, the swivel knife is used to make the bold cuts that form the backbone of the carved image. These cuts are made to a depth of up to approximately half the thickness of the leather being used, depending on the effect desired by the leather worker. Care must be taken during this step to keep the swivel knife vertical at all times, as any tilt is detrimental to the ability of the leather to be properly stamped later in the carving process.
