Have you ever dry embossed on foiled cardstock? No? If not, give it a try, and you will be in for a delicious surprise. The results are extraordinary.
The background of this card was done in just this way.
Please try embossing on foil cardstock. Or, as an alternative, try embossing on heavy duty foil right off the roll. It's a bit fragile to work with, but looks wonderful. Another thing I've embossed before, with nice results, is the flat bottom of a foil pan.
Most of all, have fun with your experimenting! I think you'll have a delightful time.
