I got the Big Shot Texture Plates delivered the other day and finally got a chance to play. After a few tries I figured out how to dry emboss the front of a card. Just the front. The results are stunning. Here is the sandwich I used.
Multipurpose Platform, Tab 1, extra piece of card stock (shim), Texture Plate, card stock card, Silicone Rubber Pad and the Impression Pad. I let one side of the card, the back side, hang out of the front of the sandwich and wheeled it on thru.
