i used to flash the H. Pass too. I usually turn my body slightly so the back of my hand is facing my spectator. It covers it a lot better. If you want to do it facing them, I would have the deck elevated a little higher than usual (between my belly button and chest) and when they look at me in the eyes I slowly lower my hands (not too slow, just natural) and have the back of the deck facing them at an angle so they cant see what's happening under the deck and with that motion I do the move. I usually just do it with the back of my hand facing them so they can't see what's happening. I hope that makes sense. Good luck!
