Hi Magic1,

Someone has PM me about this recently, so I could answer this for you. First of all, the switch is designed to have a table with, and I've never done this in a walk around situation.
In order to do this walk around, I would recommend to prepare a watch/necklace type of long box to store the paper in completely straight condition. If a spectator can hold on to the box for you, the switch can be made as if you have a table. The switch itself it's quite easy to do, it is in the act of apparently picking up a piece of paper among the stack.

Hope that answers your questions

Firstly, as a storytelling bizzarist id just love to say how much I love this trick, however I'm having sound issues with the gimmick....is there anything I can do to dull the sound as its making a very audible 'clunk'
