A gathering of thoughts, quotes and drawings. One more detailed than the other. But no rules...sketchbooks are places without rules. That's why I like to sketch so much. I often find my sketches better than the final drawing. Plenty of sketchbooks are on my shelves. Some completely full, some completely blank. Just in case, I might ran out of sketchbooks one day! So I often buy them to set aside. Do you have a sketchbook for drawing?
