Some Doodlings I did while at the Richmond Zine Fest Saturday, Oct. 4, 2014.
maybe I will embellish and complete them into full-blown Sketches, or even Drawings.
What's the rule? 
What's the definition of Doodle, Sketch, and DRawing compared to each other?   Is there some sort of standard?
I don't know.  But I know I had fun at the Zine Fest!
Any photo's of me at the Zine fest, let me know. My camera had dead batteries (my usual luck)...
