Different Props
Heres an idea that can be applied to ANY category of magic, & will help out in being original. Look at all the card tricks you know, & think of the ones that has nothing to do with the faces of the cards, like transition effects where face down cards jump from pile to pile, & see if you could do the same effect, but with different objects. Example, Piano Cards could also be done with matches, coins, sugar packets, business cards, or whatever else is around or whatever your imagination can think of. I think step one in overall originaltity is to look at EVERY trick you know, & try doing it with an object that NO one that you know of has done it with, & to do away with objects that if you were to walk up to anyone on the street & say "Give me a list of props associated with magicians", things like silks, sponge balls, canes, rabbits, doves, ducks, tigers, elephants, straitjackets, etc. So also think of card substitutes, like index cards with your own designs on them, pieces of paper, post-its, crackers, & on & on & on. YOU CAN DO IT!!!!!!!!!!
