This is an example of Dry Embossing:
The sunburst was embossed on white cardstock, and then treated with chalks to look like marble. It was ripped to age it, and then mounted on a dark red card stock, and then on a white card. Gray and black chalks were rubbed on the card stock and the card to age the look some.
I couldn't really scan the inside of the card, because of what was used. A putty colored card stock was folded in half, and cut with a template that looks something like this:
(This is not the card that I sent out, but I think it's pretty cool!)
