A friend of mine wanted a portrait of a collegue in a ?andy warhol? style. I suggested using different colors, but on the same image, using this technique I?ve used a couple of times before.
It was pretty tricky. I had to use a cover paper with one fourth of the canvas cut out and the masking tape stuck to the masking fluid, and getting it to line up wasn?t easy either, but in the end, it worked out pretty well.
