I am terrible. This must be very valuble art, but looks to me like a DIY. Buy 2 pcs of canvas and make a swirl on #1. Put "2 one top of #1. Move them a bit sideways while the paint it wet. Remove. Done. - This is abstract bacl wings painting.
Bubble Painting Envelopes = 1/2 cup of water, 2 Tablespoons of paint, and a few squirts of dish soap in each container. Blow with a straw into the cup to make lots of bubbles pile up on top of the cup, then press paper to the bubbles so they pop and leave bubble prints!
