Hey guys, I'm in need of some help for this idea I have for my school graduation. My principal does not believe that it would be possible to do a card trick in such a large venue as a church (more than 200 people possibly) and won't accept my idea. I just wanted to know if you guys think that I can perform some card forces like the Cull Spread (that's as difficult as the forces get for my routine) with cards that are maybe 10.25 inches by 14.5 inches. I'm thinking that jumbo sized cards will hopefully allow everyone to see the cards. Tell me what you guys think, I really want to do this for my graduation.
