Paint Brushes
Again, I do not have any particular brand favorite for paint brushes. I prefer imitation sable or krylon fibre folk art brushes for majority of my work. I use these brushes intil they show the first signs of fraying, then I trash them. Most of the surfaces I work on are fairly grainy and abrasive, so the brushes do not last long.

Brush sizes I use are:
00000 - 000 - 0 - 1 - 2 - 4
There are others, but you do not really need a full range of them, these will suffice.

The 00000 is micro small and is an excellent detail brush.
The 000 is larger and holds a bit more color than the 00000.
The 0 is excellent for precise work that requires more medium or color to complete.
The 1 is a good companion for the 000. Holds a nice amount of medium.
The 2 and the 4 are bigger tipped and are great for larger fill areas.

Never vie for cheap brushes they will cheapen your work and are a nightmare to use, on the other hand, don't fall for the hype over the "top of the range" brushes either. These are usually monsterously priced and, half the time, their worklife fails to justify their cost. Try and buy is the rule here.
There are lot of brand name brushes about, just ask at the art store which one is the best seller. They usually wont lie to you if it leads to a sale.

Mediums

Pigmented Artists Ink
I like these inksand, as I aways say....they are easy to apply and tough when they're dry.
Pigmented inks differ from other inks because of the colorfast qualities they have. Other, non-pigmented inks will fade very quickly, whereas pigmented ink is far longer lasting. You may note here that I neglected to say permanent.... It is widely recognised that the colors yellow and red will fade quicker than any other colors regardless of the type of medium. A good example of this is can be seen on old, peeling roadside signs, if they have red or yellow lettering on them then I'll bet you it's barely readable.
Pigmented Inks are transparent and water soluble when being applied and rock hard and near water-proof when dry. They are available in a large range of colors and are great for use on paper, wood and natural leather.
Brand-wise, I prefer to use Art Spectrum or Winsor Newton.

Airbrush-grade Acrylics
You will notice I state Airbrush-grade, this is important to me, as the quality of this form of Acrylic Paint is high. I also means I can brush or airbrush without having two different acrylics to keep in stock or store.
Acrylic Paint is water based and is fairly transparent. Like the Pigmented Ink, Acrylics water soluble when being applied and rock hard and near water-proof when dry.
Brand-wise, I prefer to use Dr PH Martins Spectralite or Createx Acrylics.

Spirit-based Leather Dye
This dye is intended for dyeing Natural Leather, but I find it excellent also on Paper and wood. The dye is Metholated Spirit based and is transparent. It can be brushed or airbrushed and dries very quickly. It is usually available in a range of colors and is available at most saddle shops and craft suppliers. Highly Recommended
