The challenge- Mix a color spot, put it down, mix another, put it down.... It is an excellent exercise in seeing color spots and their relationship next to one another. The final painting should look kind of patchy. No blending! OOPs I did blend a little in some areas. I had a devil of a time keeping the patchy look on the label using only the half inch bright brush. All in all I think it made me looser. I think I will do another setup and do that challenge again. I love the look.
I am supposed to be looking down on the bottle. I hope that came across ok. I think I can do better next time.
