If you would like to make these, you can find instructions for them on
Splitcoaststampers. The only thing I can add to it, as that I used Stazon and Palette inks on these and there are two ways to make sure they won't come off. One is using Krylon's Acrylic Sealant spray (which is what I have done) and someone else recommended baking them. I don't have an oven for crafty stuff, so I opted for the spray and it works.
Have fun making them and sure would love to see what you come up with, so let me know, if you made some!
