So let's say you carry several decks of cards to your gigs. A couple of regular decks, maybe a Svengali and a Brainwave deck, and a Si Stebbins stacked deck. Does anyone have a method of labeling these decks so that you know one from another? I've noticed some magicians used several deck flavors (Bicycle, Tally Ho, etc), and that may be enough. I just wanted to explore the topic, as I seem to have a lot of red Bicycle decks around, and all my trick decks are also red Bicycle.
