Pen and ink leaf drawings

I'm using my day off today to prep a lesson for the charter school I will be teaching at this Friday. Students will be using India Ink and a quill (feather) to draw with the ink. I use a disposable container to put the ink, since it stains. I also put down newsprint on my work surface. Students will start with pen and ink techniques making a value strip that practices the techniques going to dark.

Then using pressed natural leaves students will draw a contour outline of the leaf and use the pen and ink techniques to draw the leaf.
