I drew this with two different kinds of green ink, watercolor ink and ballpoint pen ink. I wish I had more details about this boy and his hat, but alas, I don't. :o( As you can tell, I was more interested in his face than his hat.
The crappy Bic pen I used wasn't so bad after all. It's drying up which was to my advantage. It didn't leave globs of ink on the page. As a writing pen, it's not so great.
