Do it on fondant for the best results, less stress for you, less chance for the bride to complain, and they can peel it off. There is still butter cream underneath,so tthere's no sacrficing anything! Seriously, tell them to peel it off because for that look, it's best on fondant, period. The aversion to fondant cracks me up, when it's so easily removed, and it's like it was never there.
AZCouture: makes perfect sense. (as per usual)
I can't stand the thought of putting metal leaf in my mouth.........Haven't you guys ever bit into a piece of foil coated hamburger wrapper and had that screaming shock of foil between your teeth.
