What is a flexagon? A flexagon is made up of regular polygons (a figure with three or more straight sides) and are folded together in such a way that they "flex" and show more than the usual two faces of flat surfaces. The flexagon is based on principles which appear elsewhere in daily life, such as doors which are hinged to open either way, and in magicians props such as Jacob's Ladder Tumbling Blocks and the Himber wallet. Complete instructions and several pages of actual patterns, dozens of well-drawn illustrations plus some beautiful Bible applications are included.
