Two test sheet overlays of flexible opaque plastic (8.5 x 11 inches); one has two black, horizontal lines across the center and is marked "Test Sheet #1"; the other has two black, horizontal lines across the center and is marked "Test S #2." One background overlay sheet of clear flexible plastic (9 x 8 inches), mostly blacked-out leaving a pattern of clear quarter-inch circles. One template of semi-rigid black plastic (8.5 x 8.5 in.) featuring a 6 x 7 grid of half-inch square cutouts.
