Palette knife practice. With watercolor. Just to see what would happen. I mixed puddles of paint, and then dipped the knife. Observations:
- Mix thicker paint next time.
- Mix more paint. (Larger puddle).
- Don’t go back into a wet area.
OK, that last one was an accident. I thought the paint was dry. But I am not upset by the result, the yellow with the bloom. I have seen halos like that, in a misty seaside sunset.
And those are all things I knew. This little practice just reinforced them. I used a long rectangular knife. It covered more area, and helped to blend the transitions.
