Check out the blog of award winning author Mayra Calvani. She has a great post today about plotting your storyline. It is an excerpt from the book by Claudia Suzanne titled Begore Copy Editing. ( I apologize for not having the title in italics but the editing bar in blogger isn't working today)
This process for plotting is a "Meet in the Middle" process and is a great way to get an overview of how your idea looks from beginning to end and back. Check out the article at http://mayrassecretbookcase.blogspot.com and let me know what you find.
