Here's a sketch I did of Chloe's little backpack. I find that now that I'm a parent, I'm making little notes and sketches everywhere of the funny things she does and says. Most of the time it's just a quick note written in my cheap planner. Occasionally, it ends up being one of these full blown illustrations.
I find it amazing looking back at this stuff at how much of it I would have already forgotten had I not written it down somewhere.
