The rules for doodle art are as follows: Start with a never ending loop, 'take a line for a walk' Fill the areas with patterns and shading, use handwriting patterns, geometric patterns, cartoon pictures; whatever comes to mind. Once the areas are filled build the shape out to fill the page. Don't use a rubber! If you make a mistake see how you can use it in the pattern. Only sharpen your pencil if it is absolutely necessary. Only follow the rules if you want to!
