Hi I was curious to where I could find more info on a routine I have seen twice now where members of an audience have four cards and face over are told to rip the packet in half and follow instructions and then the patter leads to he/she loves me / loves me not and discarding one half of the cards down to one that matches perfectly with a chosen half they removed at the start.

It is by Woody Aragon.

Thanks do you know which of his lectures it is in ?

Found it - thanks

Glad you found it. I figured someone who knew would jump in and let you know. I have no idea where Woddy teaches it. In just remembered it from the Penn and Teller Fool Us show and I also have seen it taught (recently) on Aaron Fisher's Conjuring Community Site in a video called "Woody Aragon Love Cards" but it was taught by the CC Staff. You have to be a member to see that one (and I cannot remember if P&T taught it or just performed it on the show) so I wouldn't have been able to help past letting you know the Originator (as far as I know) for the effect you were asking about. It is a very cool effect though and a fantastic way to include an entire audience from 1 on 1 to a 10,000 seat arena.

It is in "A book in English", the effect is called "How to find your other half"
