I have heard you can use chocolate transfer sheets directly on fondant.... How do you do that?

It needs to be ironed on. Seems like a touchy process. Haven't tried it myself. There were some pasts posts on this topic, but they seem to be lost on the crash. There's a website where a woman is selling a video and an iron for this technique.
