The storyboard process I use I learned at a workshop with Carolyn Coman. Basically, you get a sheet of paper that's large enough to fit enough squares to represent each chapter of the book. Then you follow these steps:
1. Think of a scene with the strongest image that best represents that chapter. Draw it as best you can in the first box.
I love writing fiction, but revision can become frustrating. There's so much going on in a novel I've got index cards pasted across an entire wall. And it's still not enough.
This storyboarding tip is wonderful.
