Such a smart idea (feed old book pages through a printer to make unique silhouette art). Not gonna lie, I'd probably scan in the old book pages first, and use the scan for the final print. I love my old books, I don't want to cut them up.
Master AN art! Master a skill! What the fuck are you? Become an intellect, the art of observing, it's not an art, it's manipulatively, what is your motive? Master something. Manipulation is not an art.
