I recently visited Loretta Stephenson's blog Art By Retta, and she inspired me with her Doodles. What was so refreshing was she did her right on her wall! The picture started on one bathroom wall and wrapped around to the other side of the room. You can see the doodles by going to her blog.
Why am I raving on about doodles and what has it got to do with writing? It's the imagination at work in a free flow thinking process. I tried doodling with my writing by letting a story be what it wanted to be as I wrote. I found it went in a direction I never expected and a whole new portion of the story erupted before me. Now I can add this section to my already existing story and continue from there.
Does doodle writing work for everything? I doubt it. I think it's a way to loosen the cobwebs and start the engines when you need refreshing. It helped me focus on a problem I was having with my story and separate it out from the rest. When I worked specifically on that portion, it became clear and easy to define.
Try doodling as a source of relaxation for your writing. It goes as deep as your imagination will let you. Plus, it will give you a new perspective of your current work in progress. Is it a waste of time? Any time you are working on your creative process you are strengthening your writing abilities. Give it a try... or have you already?
