The Palm Spin

In this trick the club starts in the same position as for the thumb spin, but as soon as it starts to turn the hand is placed flat, palm up, and the club rotates there by itself until friction causes it to stop:

I find that the best time to open out the hand is when the club has turned through 180° and the body is pointing back at you. Some practice may be needed to keep the club in one place as it spins on your palm, but again the answer is lots of little practices rather than one big one.
