Shoebox swap is where you prepare the makings for a project, usually a card and bring enough for everyone at a table of 6 to 8 people. You bring cut paper, stamps and ink for your project in a shoebox or some such container. You then rotate around the table doing each project and at the end of the day have 6 to 8 different cards. The afternoon varies depending on the organizer
