Tip: Erasing Charcoal Pencil Drawn on Acrylic Paint

I made a rather pleasant discovery today while drawing this face in charcoal pencil. First of all, I don't know about the rest of you but most of the time, I do not draw faces I like on the first try. It usually takes me a few passes to get the face or drawing looking the way I want it. This means there is a lot of erasing going on. The other day while browsing the craft store I found an eraser that was supposed to erase charcoal in addition to being good for erasing graphite.

Eager to try it out, I used it while drawing this face but what I discovered was that the eraser alone was not enough. So, I lightly touched the tip of the eraser with a damp towel and voilà! It worked like a charm in erasing the charcoal lines. For a bit more precision and control, you might also try some Q-tips dabbed with a little water to erase then use the dry end for cleanup. Pretty cool eh? Now I can paint her.
