It's hedgehog's birthday and mouse has laid on a little spread, complete with jam tarts and big birthday cake. Cling style rubber stamp from Penny Black. The image is about 10cm (4") tall. Slapstick is Penny Black's new range of unmounted rubber stamps. You get the same high quality rubber stamp, but instead of a wooden block, there is a layer of grey padded foam that will stick to an acrylic block (sold separately a clear stamp, without needing any adhesive. The design is printed onto the back of the foam, so you can see it through the acrylic block, and clear stamps, you can attach the stamp to the block and remove it again as many times as you like.
