This card is super cool and easy to do. Just glue a piece of DSP to your card front, run that through an embossing folder, and then gently sand with a sanding block. Yes, it has been done before, but having it glued to the front first then carries the debossed image to the inside of the card. Trust me it's a nice touch.
