These turtle coasters have been printed with my photographed design of 117 naturally-formed heart-shaped rocks from my collection of three decades exploring Maine’s beaches & islands. The original flat-lay art was 3 feet long when I photographed it outdoors from a ladder. • Art is heat-absorbed into sandstone by CoasterStone (USA) for moisture & heat absorption • Larger than standard coasters at 4 1/4" square, they have a 1/4" depth and a cork backing with a label which reads: Original flat-lay photograph designed with heart rocks shaped by the surf along the coast of Maine • Each is individually packaged in a cellophane sleeve with SKU sticker By searching "turtle" in my shop, you'll find this art also available as candles, note cards, notepads, magnets, and prints.
