I love making these domino pendants. I first made them about 6 years ago by accident. I was working on my stamped dominoes - i had read an article on them and thought it was a great idea- and while I was refiling one of my art pens some of the ink fell on a domino.. the rest is history. I heat set the inks once I am happy with my mini painting and then cover it with an epoxy/resin (which I apply by hand on each tile) for protection. Hope you visit my etsy store http://www.etsy.com/shop/MoonSirens or http://www.indigomoonmarlton.com to find wearable art pieces for your holiday gifts!
