I used 6 sheets of TP for each casting. After die cutting the sheets using a Matt Stack die, I just laid my stamp face up on my granite kitchen countertop, laid the die cut TP on top, added a little water on top and pressed with a kitchen towel and then a paper towel until I got most of the water out.
Then I just laid them out on a cookie rack to dry (overnight). The hardest part of this whole thing was figuring what to do with them once they were dry. They are a bit delicate on their own, so I was afraid they wouldn't hold up by themselves as a tag. I tried mounting them to the same die cut shape cut out of cardstock, but found that the shape distorts once you add the water. So they wouldn't fit nicely on the die cut shape of cardstock.
Here are a few of the ideas I came up with.
One of the die cut shapes I wanted to try out was the lace edge heart in Limitless Layers Hearts. I wanted to see if the little lace edges would die cut and stay in tack once wet. I was very pleased with the result! I just used a little bit of water in the center of the heart and tried not to get the edges wet. I use a sentiment from Love and Marriage. I put the heart on top of a little hexagon shaped box, which I covered with pretty patterned paper. Tied it all up with a little gold cord.
