A nice effect in principal, but with major floors. First of all the four dots you 'draw' on the
gimmick are utterly perfect circles, which is impossible free hand.
Also requires a triple
lift with the gimmick. Given that the gimmick is two cards in thickness, this becomes a quadruple
lift, and to anyone with a pair of eyes in a well lit place, the method is quite visible.
I think it really depends on your timing. If you do your turn over brisk, it goes by unnoticed. Also another tip is to tilt the deck so the top faces the spectator. If you have the deck tilted this way from the start of the trick the only time they can see the thickness of the mlm packet is in your brisk turn. Keeping that packet in motion makes it really difficult to spot. I have used this strolling and had no one call me out. I hope these tips help. If you still don't feel comfortable performing this version, you could just do the shake style routine that Rick Lax does.
