Before we start working with the cards, wash your hands. Not only will this facilitate easier card handling, but it will keep your nice, new cards clean and slick.
When I first start learning any trick or flourish, I always use half the deck. Now my hands are smaller than most, so feel free to use whatever amount of cards fits your hands best.
Please keep in mind: I am not a professional of any sort
What you're about to see is the product of a little practice and some luck. Don't get discouraged - just work with it a little here and a little there until you get comfortable with it.
