The gimmick is perfect. I have made many of these over the years and they don't last. This Tyvek
gimmick folds tight, the colors are spot on and it will last for a very long time.
I think
that the complaints about the altered back design are rooted in an unnecessary fear that it will be
discovered. It won't. The coloration and organizations of the alterations make them invisible when
handled properly. Take it out, show it briefly, and get to business. No worries!
I would
recommend getting a 2 dollar bill to end with, claiming that "with the exchange rates I can double
my money!". It doesn't have to end with a large bill.
