Alan Rorrison - Benjamin
Hello and welcome to Benjamin. In this effect you will have a card freely selected and tear it into a frame. You will then slip it into the opening of your shirt and make it pass through the button inexplicably. At this point the spectator can tug on it or even inspect it and see that it is truly linked on there.
The spectator can check everything out. The card! The shirt! EVERYTHING!
You will also get my moving button routine where you take a button that is sewn onto your shirt and visibly move it to a completely different location on your shirt. Completely examinable!
