A luminous yellow square occupies the center of a soft gray field, its edges crisp and its saturation absolute. The composition is spare and meditative, letting the intensity of the single form command the entire space with quiet confidence. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
