Tutorial - Basic Techniques - Overbrushing/Drybrushing

Following on from the last Basic skills tutorial (which can be found here) we were left with a Space Wolf base coated and washed to really darken those recessed areas (see Picture below)

This tutorial will introduce the first step in highlighting the raised area of the miniature, and this step is called Overbrushing, while often called drybrushing, this is actually incorrect as drybrushing and overbrushing share the same technique but differ in paint saturation.

Tutorial - Basic Techniques - The Wash

I was in my local Games Workshop yesterday to do some painting and due to some case confusion picked up my space wolves not my high elves thereby confounding the painting plan, however being in the store anyway I was chatting to another fellow hobbyist, and as these thing always do talk very quickly turned to painting techniques.
It transpired that my fellow hobbyist had little experience with the wonder that is the world of washes and it has occurred to me that there may be a few painters out there that don't know just what washes will do for them.
So for my first ever Tutorial I have chosen this very topic.
