After loading up these last few sketches, I got an idea to use them (or others like them) as a backdrop for my portfolio site, to add color and interest. I quickly mocked up a couple templates to see how they would look.
Just because it is a sketchblog doesn't mean it shouldn't have some color. Here is the new header I made. Composited from some sketches with the Sharpie Fine tip pen, and overlayed in Photoshop.
