You wouldn't think that an artist would need to take a class about it. This artist would. As a child, I would watch other people do it and envy their freedom to mark up a page with any old idea they had. I couldn't do it because the nag in my head wouldn't stop critiquing every thing I did. I've managed to put that nasty old grump in the back some where, but it still keeps shouting at me from the closet.
I didn't work at art seriously for a long time because I didn't think I had any ideas. I need a way to unblock my thoughts and dreams to let them flow through me and out onto the paper. These doodles aren't the end product I'm looking for but perhaps they are the route.
