Basically, on my computer, I created a new Word document and added a large, black rectangle that took up almost all of the page. I printed the image several times using a laser printer. It's important to use a laser printer because it's the toner that works as the adhesive for the Deco foil when it's sent thought the laminator. Then I die cut several images using dies that I had on hand.
To apply the Deco foil, I placed the die cut images onto a piece of typing paper that I folded in half to create a folder to send through the laminator. Place a piece of Deco foil cut to size on top of the black print side of die cut with colored side of Deco foil facing up. Then I ran it through my laminator. Amazing results - love it!
