A green and white checkerboard pattern warps and swirls across the composition, creating the illusion of a three-dimensional vortex pulling inward. The repeated squares bend and twist in a hypnotic rhythm, transforming a simple geometric grid into a dynamic, almost dizzying optical effect. 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.
