This is an excellent effect. Unfortunately, I'm apparently a moron and can't get the fold down.
I've practiced it for two months now, and gone through no telling how many cards, and still it's not
to the point where I'm comfortable with it. It can be performed without being perfect, of course,
but I'm disappointed in my ability to learn this particular move. It's not hard, it's simply
something that hasn't yet clicked for me.
The effect is excellent, and impromptu for all
intents and purposes. This makes it a keeper for sure.
