Interlocking rounded squares in soft aqua form a seamless, rhythmic grid against a deeper blue ground, creating an optical tessellation that shifts between figure and background. The repeating pattern evokes mid-century modernism with its clean geometry and restrained palette, achieving a hypnotic balance between order and visual movement. 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.
