After some cutting down I've now got a lot clearer idea of what is going to go on each page.
2 (inside cover) - An intro into blending modes, what they are, where you can find them.
3 - A basic guide to the terms of blending modes, mainly the blend colour, base colour and resulting colour. These three terms are crucial to the explaination of the sixteen basic blending modes so I figure it is important to establish what I mean by each of these terms. I'm including some visuals for all the visual learners out there!
