Place the card in the center tip of your middle finger. The card should balance on your finger and you can test this by wobbling the card on your finger left and right without it falling off of your finger. Try to spin the card with your other hand. If it falls off your finger it may have been off center. Next, use your thumb, placed on top of the card to stabilize the card. Raise your thumb above the card. With your index finger, lightly pull the card toward your palm and generate a spinning motion. It may take practice in order to perform this trick with minimal effort.
