A four-panel composition of bold black horizontal and vertical lines creates a geometric rhythm across a white ground, each quadrant rotating the line direction to form a dynamic optical pattern. The hand-drawn quality of the marks and their irregular spacing give the precise grid an energetic, almost textile-like texture that suggests movement and depth. 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.
