While working on a new 12"x12" painting on Thursday of a Queen Angelfish, I had one of my larger bristle brushes between my teeth sideways. The brush was loaded with beautiful bright cadmium yellow oil paint. As Murphy's law would have it, I dropped the brush right smack dab onto my nearly finished painting. Instead of brushing out the blob of paint and risking smearing it around, I took a small palette knife and tried to lift it off. In the process, it made a very cool mark on the fish. Even though it would mean changing the order of how I had originally painted it, I decided to keep going with it and see what would happen. I ended up re-working the whole painting and am actually ok with the results.
I wish I had had time to take a photo of the first version before the brush fell on it so that you could see the comparison.
