Inspired (a little) by Lichtenstein's Perfect/Imperfect paintings, where continuous geometric lines move around the page from edge to edge (perfect) of from off-edge to off-edge (imperfect).
In Lichtenstein's originals, the spaces between the lines are filled with his trademark fills (dots, lines, gradients).
Here I have used three perfect stencils, laid on top of each other and then created a fill with a complementary colors and shades.
Similar constructions follow, generally made from three stencils with colors and shades determined by the selection of stencils.
