I'm having a few problems when trying to practice the pressure fan. I begin with the deck resting on my index and middle finger, I place my thumb above. And with my right hand I grip the deck with the index,middle, ring on top and thumb on bottom. I start by bowing the deck downward and continuing in a circular motion. The problem I have is when I start the card on top of the deck stays behind. And when I somehow mange to get the card on top to stay with the rest of the deck the cards in the middle shoot out. Also when I sometimes get halfway through the dan the cards stop at the base of my palm, is this because of the positioning of the cards? Any tips would do. Thanks a lot in advance!
