Last year I started learning gambling sleights. Currently I am happy with my performance level of the moves, but despite my practice I'm still noticing this clicking sound for some of the sleights (i.e. Bottom Deal, Diagnal Palm Shift, Classic Pass, etc). The sound is faint but since I hear it, I worry that someone else will hear it and catch on. With that said, my question is if any of you have advice on how to diminish the clicking sounds made by the playing cards.
