Does anyone know if there's a way to use either of these on chocolate? (I'm trying to come up with an edible playing card on something onther than fondant).

Thanks for any help or ideas!

You can draw on wafer paper w/food writers. That's probably what I would do.
I really don't see any way to do a cho transfer - lots of work!

I'm sorry, I guess I was vague in my description, I apologize.

What I'm looking to do is make chocolate playing cards by adhering a pre-printed wafer paper graphic or edible image to a piece of white chocolate cut to playing card size. I've done it with fondant previously, but would like to use white chocolate this time with the adhered image.
