In an earlier post, I suggested making a nature journal. I try be best to practice what I preach, so I've make my own sketch journal. I'm interested in biomedical illustration as a career, so this is good practice for me :) So far, I'm trying to draw all of the organic objects in my room and them move on outside. All of the sketches are in normal graphite.
My journal is a thin kraft paper Moleskine
I found the logo in a LIFE magazine from the 1970's
