NO it's not tin foil or metal sheet it is foil/metal tape, yes it is a tape. This is what you would use around your dryer vent and you get a bunch of it for cheap. All you have to do is peel and stick it to a piece of card stock, remember to overlap it just a little you don't want the card stock to peek through. You might get a few wrinkles but they can be rubbed out pretty easily. When you emboss it you really can't see the seems and wrinkles unless you really look hard. I didn't want this card to be so shinny so I took some black acrylic pant and gave it a quick brush over. See ya tomorrow.
Have a Wonderful Day, Candice :-)
