A few years ago I participated in a swap which involved stamping on Dominoes. I chose not to go the standard card route, but instead created a little collection of words to use as daily affirmations.
When stamping on dominoes it is important to clean them with a solvent to remove any oily residue left by ones own fingers. After cleaning the dominoes I inked up my Great Impressions (South Africa) stamps with Versamark and embossed them with silver embossing powder. I discovered that dominoes can heat up quite a bit so be careful when touching the domino after you've heat set the embossing powder.
I printed the descriptive card wording on my computer, and stamped the reverse side of the card with the Dragonfly from the HERO ARTS Kimono Silk set of stamps.
I presented them in this pretty lilac organza bag, along with a descriptive card and white feather - presentation is everything!
