I made these using a domino, alcohol ink, and a keychain . I drilled a hole through the domino. Used alcohol ink and felt, dabbed it over the plain side of the domino until I liked the color/pattern, let dry. Then stamped it with permanent ink, and sprayed it with high gloss varnish. The varnish made the colors look more milky then originally. Before the varnish was applied the texture was more detailed and more vibrant. Next time I am going to try decoupage glue to seal it. Hopefully, that will make a difference. Once all was dry, I inserted a large ring and attached the keychain. So many ways to decorate these dominoes! I will be doing more experimenting with it.
