... is that sometimes the graphite smears all over the place a few days later, if you keep your sketchbook in your backpack with you.
I have some fairly recent stuff I'd like to scan, but it's smudged to Hell and back, due to soft lead, my heavy cave-man grip, cheap sketchbook paper, and carting said sketchbook all over the place.
On the other hand, it's cheap paper, so I don't feel like I'm "wasting" resources with studies. It's a ridiculous hang-up, I know, but still :/
I'll try to scan my daily lunch break sketch/study and post it before I punch out for the day.
