Jesus, I have women hands,(or so my friends say) that means that my fingers are very long but my palm is skinny, I can do a lot of the standard sleights, but the palms are usually a no-no for me, just imagine, when I palm a card, the card easiely covers my whole hand, so you kinda get the point.
There is an advantage thought using small hands...it disarms the audience, most of them thinks that having big hands it's the secret, so when they see you with your small hands they are like "no way, he has so small hands!".
Get me?
