The shapes of the white spaces to create the movement is critical. Once the white of the paper is eliminated, you can’t get it back unless you resort to scraping and tearing of the paper. As I mentioned, this paper is very soft once the surface size is removed, and will tear easily. I will do some scratching in this area but not until I adjust the white spaces in other parts of the painting. It is amazing how white the whites appear once you get rid of all of the other whites.
The whites that I will keep will be for indication of movement.
