Vertical and horizontal stripes in green, blue, and yellow form a grid pattern, intersected by crisp white lines that create a plaid composition. Small coral-red circles punctuate the intersections, adding playful accents to this geometric, mid-century modern arrangement. 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.
