If you have a fully completed sketchbook or sketchbooks, what's in them? Because i often run out of idea's for mine. I hate that i'm so selective as to what goes in my sketchbooks. This often makes it difficult to draw in them. Are your books random or do you have a theme for them? I prefer random stuff. It keeps things interesting for me. Also, do you ever let anyone like family or friends flip thru your books?
