Preparation is one that discourages performance. Why aren't you manufacturing these props that take
tons of time to create? Sell them as refills. I would pay $10 for 40 of them. In fact, I might
look into sending some blank business cards out for preparation elsewhere.
You must be
confident with sleights to perform this trick. There is a LOT of heat on this business card that
you have just turned into a work of art. A LOT. I've found that even if people don't know WHEN the
magic happens, they sometimes still guess what the method behind the trick is. Seems to help when I
do some sort of slow reveal.
