I love the look of embossed vellum and I saw this card where she used stamps to stamp her background and then dry embossed over her stamping to make the image appear on the other side.
You can either use one stamp over and over again stamped onto your vellum background, that is the whole size of your card or you can use a background stamp that you trace, just remember you don't want it to intricate. You can use other stamps on top I used the same stamp as I used for the background but you don't have to.
Here is a link to the tutorial I found.

When posting use WF20 - Dry embossing. Please no combining with other challenges. I will send a goody package to a random drawn participant.
I will post my card in the morning.
