Technique

I have gotten a couple questions on how to do bead embroidery. I actually learned on my own the hard way! In my searching for better ways to do this technique, I found an animated primer that really shows clearly how this is done. You can see it here. I have made a couple tweaks to my own way of doing things after seeing it done on this animated tutorial. I am looking for a book that clearly shows different ways of adding texture to my beaded pages. Does anyone know of a good book that shows this? I would really appreciate someone pointing me in the right direction.
