So what we did was used the brayer to lay down ink and then we subtracted the ink from the plexi-glass to shape our faces and show the light versus dark places on the face.
Then we ran the plexi-glass through the printmaker (with paper on top, obviously) and got our image printed onto paper woo hoo!
Like I said, I loved this activity. I had maybe 1 or 2 stand-alone pieces, but the others that are pictured here are cut-and-collaged together from other pieces. I don't have pictures of ALL of my prints, sadly, so I'll need to take pictures of those.
(This one's my favorite)
