Tracing paper is not just for tracing.
You can draw on tracing paper too. You can draw directly on it as you would draw on any other sort of paper. The difference is that you can see through it. So when I place the tracing paper drawing on the cartoon, I can see what flowers will be covered up by the addition of a new flower. It will help me sort out the imaginary spatial relationships of the flowers in the bouquet relative to each other.
Drawing the flowers on the tracing paper rather than tracing them from the drawings I’ve made (or from the sources that I’m raiding) gives me yet another opportunity to rehearse their forms.
I will have depicted each of the flowers several times by the time I make my painting, and these rehearsals are part of the rationale of this approach to painting. Having practiced them before, I’ll have a different level of preparation. And I enjoy really learning these forms. It’s musical. It’s like practicing a piece of music.
All this process is part of creating the cartoon for a flower painting that’s in the pipeline, which I wrote about before HERE.
