Close-up magic plays to small audiences in informal settings, be it at a bar or around a dinner table.
Close-up magic is typically associated with card tricks. However, my repertoire also makes use of the everyday objects that exist wherever I'm performing - often using items borrowed from spectators.
I also use a liberal mix of traditional visual magic and mental magic to suit the moment.
Adult close-up magic is ideally performed around dinner tables or in a walk-around situation when guests are generally mingling and socialising.
