I took out three note cards and labeled them "Beginning", "Middle" and "End". I wrote 1-3 sentences summarizing what happens in each part of the story, then turned each card over and made a numbered list from 1-3. Under items 1-3 I listed the beginning, middle and end of each section of the story, giving me a really solid framework to build my story on and it's a relief to have such a simple, straight-forward format (it sure beats all my plot notes in my sketchbook, in-between drawings and notes for other things!).
Next I'm going to pull out more note cards and plug in more details in each section. Anyway, I thought I'd share my success story so far with using Doug's approach.
