So weird, my pencil felt awkward while drawing, and then when I went to erase the pencil marks after inking, the ink started smearing. WTF?
Turns out I had been drawing on the inside front cover, not on one of the pieces of paper. It has a slick coding, so the ink wasn’t drying. I’m assuming a real artist would have noticed that the paper they were drawing on wasn’t actually paper, but the backside of the cardboard cover.
