A grid of quarter-circle segments in coral, magenta, slate blue, cream, and navy interlocks across the composition, each quadrant rotating to create a dynamic optical rhythm. The color blocks shift and dance within their square frames, evoking the bold graphic language of mid-century modernism with a contemporary playfulness. 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.
