The top image is the original painting (acrylic).
It is the work of a student of mine.
If you are nearing the end of a painting and need
to try out additional elements then here is a way
to do it without putting on paint that you may have
to take off and also wreck affects that are underneath
that you like and want to preserve.
Take colored paper and cut out shapes and lay them
on the painting til you like what you have. I have
done this in two arrangements. Of course I could
have cut different shapes in different sizes, but I
think this communicates the general idea.
