Last year 2d artist did an article on my sketchbook habit. This is part 1 to the article. My sketchbook is my visual playground that I carry around everyday. Through the day I find small moments of time to sketch stuff, write notes, ideas, etc. The commuter train is where I do a lot of my sketches. The train moves a bit while I'm riding so some of the lines get jumpy. I also carry a set of markers in my backpack that I pull out and put some tone on the drawings. Sometime I think someone is going to say "what's that smell" because of the marker smell.
