To all those who are crying about this carrying card stuff let me tell you that this usually arouses a girl's interest in you. and if you are ashamed to be a magician and carry your stuff, please leave magic.
You are not a common man, stop trying to be common, you are a magician and people expect you to be odd.
Erlos, I asked the same question to Shane Street who gave some tips.
Never abruptly take out your deck (you can take out your deck while searching your pocket etc.)
Gaffed card magic hits them the hardest.
do not say "Hi, this is my magic" this will decrease the worth of your magic. Make them ask for it. Like talk about thier eyes and say that they make you remember you friend whom you showed your magic (they will ask you to show something)
end with a souvenir they can keep. (Gaff effects mostly end like that)
drop it in their hands, slowly move away with out a formal ending.
yeah, My friends most probably gonna ask for a magic from me, and I guess I'm gonna do paul Harris' Souvenir Linking Rubberbands and let her keep that band!
Hope she will find it sweet and nice! Thanks griffinjay, I also don't see any wrong with carrying a deck with you. I mean it does really add on the sense of mystery of the person. No?
Lol, do you still have any other tips? perhaps can PM me? =D
