Don't even think about crafting with anything except the No Trespassing Die and Clear Photopolymer Stamp Set from Hero Arts. There are stamps and coordinating thin metal dies in the package. The stamps feature sentiments like "warning" and "it is forbidden." Use the stamps with an acrylic block and inks of your choice (sold separately). The dies are in the shapes of a triangle and an octagon and are compatible with most die cutting machines (also sold separately).
