This trick was MADE for a sleight to SHOW the diamond move. Jump!
Flicking the card with
your finger doesn't do the trick justice.
I'm no cardist, but I DO KNOW a twirl change, for one,
looks pretty:
Your right hand has a regular Ace -- diamond pip showing -- back to back with
the gaffed Ace WITHOUT the pip. They look like one card. held between the thumb and middle finger.
Twirl change these two cards as you gesture the cards leftward -- towards a Two in your
left hand, where the thumb had been covering the pip located near the far left of the Two.
You appear to "catch" the flying pip from the Ace ONTO THE TWO. Just lift your left thumb and
thrust out the Two as your right hand twirls the Ace.
That's one way to ANIMATE the pip.
Jump pip, jump!
