I recently picked up this tiny little sketchbook just 3.5 x 5.5". I can really keep it in my purse and sketch something fast. I added the watercolor later when I was back at my desk. My kids were very excited to be in the sketch and even held still a bit for me. We've been huge fans of Manchester State Park lately listening to the California Sea Lions and watching all the water fowl. I even spotted some Surf Scoters.
