Interlocking rounded rectangles in lime green, teal, and gray stack and nestle against each other in a geometric composition that echoes the clean lines and organized playfulness of mid-century artwork. The overlapping forms create a sense of movement and visual rhythm while maintaining balance, their soft corners and layered arrangement suggesting both architectural precision and organic flow. 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.
