The hearts are 1.5 x 1.5 inches, made of polymer clay and Dremel-buffed to a high-gloss shine. The ribbon charms are also polymer clay, but since buffing was not practical they were clear-coated with MinWax water-based polycrylic.
Periwinkle (which is a rather subjective color and hard to mix!) is the awareness color for gastric cancer.


The hearts were donated to a Relay For Life team to sell to help with their effort to raise money for the American Cancer Society. The "Helping Hearts" as I dubbed them were a bigger hit than I expected and raised over $300 for the ACS.

Special thanks to AuntyM (aka MoeArt) for her generous donation, without which there only would have been 76 hearts.
