The above cards were made using a product called ScratchLite and gold outline stickers.  ScratchLite is a thin sheet of multicoloured plastic that is coated with a thin waxy black layer.  Using a toothpick or orange stick you scratch the black surface away to reveal the coloured plastic underneath.

These are a combination of rubber stamping and dry embossing.  The border around the first card was made using a stencil made from card which I cut a fancy edge using a corner punch, then a brayer was used
