A cross-section of an oak tree reveals concentric rings rendered in precise, radiating lines in black ink against a clean white ground. The intricate linear patterns emanate from the center, capturing both the geometric precision of growth and the organic irregularity of nature's annual record. Crafted from durable canvas-like poly-poplin and made to order, double-stitched with a cotton webbing strap. The everyday haul, from groceries to the beach, carrying an independent artist's work.
