I made my own foil-backed paper for this card by putting holographic giftwrap through my Xyron and sticking it to the back of some light blue scrapbook paper.
Be sure to do the stamping and heat embossing on the scrapbook paper before adding it to the card. Depending on the type of paper you use, a heat gun can melt or warp foil giftwrap.
