I see how the pencil lines in my painting tuck under a brushstroke here, and glide over a patch of paint over there.  The lines I scratch into the wet paint with the other end of my brush mimic the other, positive lines in the composition.  Those scratches uncover some of the hidden layer that lurks beneath pigment that was applied later.  The fresh brushstroke lies right on the surface, not yet realizing that it is a part of the whole.  It thought it was a complete story unto itself until I cut through it.  I reveal the foundation.  What I don’t tell it, is the fact that another layer of paint might come along, obfuscating it completely.
