Think see though color onto book pages: "Create colored gel medium (matte) paints with gelatos. Brush over canvas, thick paper, wood, plaster, or other substrate to create a luminous and sheer glaze or paint. You can also do the same with white gesso or a white acrylic paint. It creates a more pastel version of the paint and is more opaque."
Transfer picture to canvas --- Use Liquitex Gloss Super Heavy Gel Medium and print mirrored photo (laser copy). Apply heavy gel on canvas, apply photo, print side down, press photo onto canvas and dry completely for several hours. Spray water on paper and gently rub paper off. Apply one coat of gel when finished.
