Trust. This is a perfect example. I lost interest in a painting and threw or scraped paint on it from time to time. NO thought whatsoever of doing a painting. But I knew something would come out. After 6-8 months, I moved it to get something and looked at it. Hey, that looks like a tree!  I put it on my easel and stared at the glops of paint. Then I “brought out” what I saw with brush and knife. There’s nothing like this and it’s full of imagination.
