It is a simple technique that gives gorgeous results. You run your die, cut side down, on the cardstock you want to use through your die cutting machine using the same sandwich as you would for an embossing folder. The only difference is you add a silicone sheet or embossing sheet between the first cutting pad and the cardstock. The sandwich I made for my big shot machine is as follows: cutting platform opened to tab 1>cutting plate>embossing silicone mat>cardstock>die cut side down onto cardstock>cutting plate.
I used the dahlia image from the May Flowers Framelits set from Stampin Up and embossed the flower twice onto a piece of crumb cake cardstock. I then added some gold and white ink splatters. I then used the Banners for You stamp set to stamp the banner and sentiment in Versamark ink onto some vellum. I then heat set this using gold embossing powder and my heat tool. I then used the coordinating dies, Bunch of Banners, to cut out the sentiment and adhered it to the embossed card. Before fully adhering the sentiment, I added some gold thread in a nest shape behind the sentiment and used dimensionals to hold the tread in place.
I added a few gold sequins to the embossed card. I then created a top folding A2 card base made from thick whisper white cardstock and adhered a piece of gold striped vellum from the Gold Fancy Designer Vellum Foil pack. I then adhered the embossed panel onto the front of the card with some foam adhesive to add dimension.
This is a simple technique you can use with all sorts of dies. Give it a try!
