I do a lot of weird little textbook illustrations. This was one in a series showing the blood clotting process in a laceration. I think it was for an immunology book. I used Adobe Illustrator only because it had to be entirely vector. It was sort of a challenge, because I was limited to a very narrow palette. When friends and relatives ask me if I have any work they can hang in their house, I’m never sure what to tell them. I’m trying to picture this hanging over someone’s sofa.
