I love primitive native American stamps and this pony stamp from I Break For Stamps is one of my favorites. This card came about because I had some scraps of Granitx Sculpey polymer clay laying about that I wanted to use. I kneaded the scraps together just enough to make a smooth ball of clay but not enough to blend the colors too much. Rolled it out until it was large enough for the pony stamp. Stamped the pony on the sheet with permanent ink. I like to stamp before baking and press the stamp into the clay slightly. This way you get a nice impression. If you bake the clay first, sometimes it warps and then you can't get a good impression. Bake the clay according to package instructions. When the clay has cooled, swipe the edges with gold ink.
The base card is made from dusty pink cardstock. The background paper is a piece of wallpaper that I thought looked like rock strata. Wallpaper sample books are your friend. They are great for background papers. Back to the card, adhere the background paper to your card with double stick tape. Use thick white craft glue to adhere the clay piece to the card. I don't think double stick tape will not do the job for the clay piece.
