In the September 2014 issue of MAGIC magazine on page 65 is an origami dollar bill magic trick by Blake Vogt.
EFFECT: The magician borrows a spectator’s dollar bill. He folds it into a simple small rectangle.. Then it instantly changes into an origami shirt that can be handed out.
It sounds like it might be a similar trick to this classic....although I could (and probably am waaay off).
Looking up Blake Vogt (cited in the article for the bill effect), I found this:
I'm guessing it might involve using a magnet and possibly destroying (cutting up) a piece of a bill to fit the denomination over the ring (like this trick).
Read the reviews by people who purchased this trick.
