In reverse painting, you paint directly on the glass, starting with the foremost details and work backwards in layers. It makes painting actual things difficult, but I love it for abstract stuff. I really like the way the paint looks on the flat glass as opposed to on a canvas. It's smooth and shows the brush strokes in interesting ways. The paint also behaves differently on the smooth surface, so that should be fun to experiment with. I actually already have a lot of different slightly crazy ideas that I’m excited to try out, but I want to run through some fairly standard stuff first to get the hang of it.
