Happy May - Spray and Play!
I've been playing with backgrounds again. These are done with Dylusions sprays. I put a big piece of freezer paper (shiny side up) on the work table, sprayed two or three colors, then pressed white bristol board into the spray. Some of the bristol board had gesso on it, some was plain. The one thing I kept forgetting was to spray water onto the freezer paper before spraying the inks. Makes for a much nicer blend of color when you remember to do that!
