Hello,
Where can I find instructions for a card trick called "Tear-Able Cards" where the whole audience does a matching card trick? each person has 4 cards that they tear in half and shuffle. Through a process of elimination they "magically" end up with 2 matching halves.

Thanks,
Dennis

I think this is what you are looking for. You can purchase the download here:

or find the written description in Woody Aragon's A Book in English.

Thanks so much!
