While perusing the Internet, I can across a photo the Elisa Strauss of Confetti Cakes did for Swarovski a few years ago. It is a photo of a piece of cake absolutely covered in crystals, but it was also absolutely inedible.
After thinking about it, I decided to add my own crystals to the cake, but in a much smaller dose, just to give it a bit of glamour. I also added Super Pearl Dust to all the sugar bows, for a glittery glow when hit by low candle light. Not quite a Swarovski covered indulgence, but close!
