This unique and original book presents a series of simple but fascinating puzzles that are set and solved by folding paper. They will challenge, amuse and perplex you for hours. The puzzles range from absolutely easy to seriously difficult but they can all be solved without any specialist knowledge of either origami or mathematics. A little insight and intuition, backed up with some basic trial and error, will show you where the often surprising secrets lie. This second edition has been fully revised and expanded to include many new puzzles, challenges and solutions.
