I love seeing how people work behind the scenes too! <3
I've been asked this before, so I have
something posted already, conveniently! I actually don't draw in a sketchbook, for whatever reason I don't like drawing on bound paper. So all my stuff's on loose printer paper, which I love the smoothness of and find scans by far the cleanest. I almost always work with .5 mechanical pencil and get real grumpy if I have to use .7 or larger lead, at least for anything detailed. And then I keep it all in
these folders, to poke through years later when I need a laugh. (:
