I though I was early...but I'm not the first. So, for my last post of the day, here's my answer to the challenge, which was to make a monoprint.
I used printing ink for this, the ink I use for my lino-cuts. I rolled black ink onto a piece of glass and drew in the ink with a rubber-tipped pen. Then I pressed in face down onto my paper. The result is "Backyard Abstraction."
