"Bubble"

that's the frame---'bubble'   so I dragged out my iridescent ink and pearl-ex powders.  I played with all sorts of paper (dark and light) hmmmm.  This is not as easy as I thought.  Here is my result on watercolor paper using the peal-ex powders mixed with water. Definitely not ready to hang in the Metropolitan Museum of Art, but good to get creative juices flowing.
