These mermaid coasters have been printed with my photographed design of 129 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 from a ladder outdoors. • Art is printed on sandstone by CoasterStone (USA) for moisture & heat absorption • Larger than standard-sized coasters at 4-1/4 inch square and 1/3" depth with cork backing • Cork label reads: Original flat-lay photograph designed with heart rocks shaped by the surf along the coast of Maine • Packaged in cellophane sleeves with SKU sticker By searching "mermaid" in my shop, you'll find this art also available as a sandstone trivet as well as candles, note cards, notepads, magnets, playing cards, and signed matted prints. Thank you for visiting!
