I like when you work with charcoal that it steadily works its way everywhere in your surroundings. Hahaha! I used to have an easel setup and all I did was smudge charcoal all over it and underneath it, it looked like a slew of tiny black smudgey ants were lined up (because the charcoal would fall off the paper and slide down into one little uniform pile). It still makes me happy to think about =)
