I've just come across a terrific blog by Teo, a bookbinder in Portugal. Her leather bound books are amazing. She also does edge painting on her books and she has written a post that simply and easily describes how to do edge painting. Here's the link: Edge Painting
I've added some more examples of edge painting by other Bookbinder.
I've also provided the link in the sidebar under blogs.
