A checkerboard grid of nested squares alternates between deep forest green and soft periwinkle blue, creating a hypnotic tessellating pattern across ten rows and six columns. Each square contains concentric rectangular borders that recede inward, producing an optical depth and rhythmic visual pulse that draws the eye continuously across the composition. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
