Narrow vertical pinstripes in chartreuse and white alternate with metronomic precision across the composition, creating an optical rhythm that suggests movement and energy. The tight, evenly spaced lines generate a sense of quiet intensity, balancing minimalist restraint with subtle visual vibration. 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.
