Collage With Black Shapes

I have been experimenting with some collage techniques from a book my friend Rosie brought to our Thursday afternoon painting session last week.  This particular project uses torn black paper shapes, torn white tissue, and torn shapes from the inner lining of a sheet of Bounty paper towels all collaged to a piece of mat board with acrylic matte medium.  After it dried, I painted with watercolors - yellow ochre and burnt sienna with accents of white gesso.  I found this to be an interesting process.
