I've seen similar things done with chocolate mints but I used chocolate coins - Thorntons coins were the best ones to use as they were all the same size but I also used Cadburys (a bit more expensive but I have to say they were also a bit yummier).
I glue gunned a 10cm piece of curling ribbon to one coin, then glue gunned the 2 coins together (the glue cools instantly so it doesn't melt the chocolate). I then mounted a stamped image onto a scalloped circle (make 2 of these - one each for front & back). I then attached the scallops onto the coins with a craft dot, and voila .... as Nigella would say, "how easy was that!"
Happy Crafting
