I find it much easier to work on a piece of paper that is not white.  Something about the pristine witness keeps me from putting any marks on it.  So what I usually do is cover an entire sheet of paper with watercolors.  A wet on wet: spray the piece of paper with water, then start adding watercolors.

I used Color Burst by Ken Oliver, a new and lovely product.  Then I doodled with black micron pen and gel pens.  Fun!  And Zen!
