These silicone stamp texture mats are created with heat-safe (to 400F) rubber. You can stick them to an acrylic block to make them stiff like a rubber stamp, or you can fold them and put clay between them for allover texture (think about pendants and earrings with texture on both sides!) Use them with inks, powders, and even pour resin on them to cure into a texture. Bake liquid clay on them in the oven! These come in orange or blue silicone colors.
