Before performing, list the tricks you know how to perform.
Arrange the tricks in order from easiest to hardest.
Choose a small amount of them and decide how they are best organized. Remember that a magic routine should seem like one BIG trick, not a series of small tricks.
Transitioning seamlessly will not allow spectators to think you are doing something else. It will all seem like one trick.
Start with a card trick that involves the spectator memorizing a card.
After the trick in Step #4, move onto a trick that involves the SAME chosen card. You are actually doing two different tricks, but because it involves the same card, it will seem like the same one.
Continue with that chosen card until eventually letting the spectator keep the card. Since you no longer have the card, you are forced to move onto another series of tricks.
See how this works? You organize them in a logical fashion that allows you do present multiple tricks as one and then seamlessly move on.
Now that the card tricks are over, bring out a coin, or take your routine into another direction.
For instance, you can borrow a quarter and start with some disappearing quarter tricks, slowly transitioning to the quarter into soda can trick that Wayne Houchin created.
Always leave them wanting more! Stop transitioning after you reach the climax of your performance. At their biggest reaction, NO MATTER WHEN IT COMES, walk away.
It will give them the same effect that a cliffhanger in a television show or movie can give.
