White triangles descend diagonally across a beige ground, each overlaid with fine black vertical lines that create rhythmic texture and depth. The composition balances geometric precision with organic linework, producing a hypnotic, nearly optical effect through the interplay of pattern and negative space. 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.
