I started with 4 pieces of fabric the same size stacked one on top of the other. I painted some stripes in ProFab paint thickly. Then I misted and misted until the entire stack was soaked and covered it with poly film. I pressed with my fingers (maybe not hard enough) and left it covered over night to migrate through all the layers.
Next day I separated the pieces of fabric and laid them out to dry on a sheet of poly film on the floor. The original sheet of poly had lots of paint on it so I took a monoprint.
