From the introduction: "This book is the first to explain basic pop-up techniques comprehensively, and to show how they have been used creatively by professional paper engineers, amateurs and students. It attempts to show that, although in the hands of a master pop-up can be a remarkably sophisticated construction, the techniques themselves are delightfully simple and can be used creatively by anyone...The aim of 'The Pop-up Book' is to enable you to master the techniques for constructing pop-ups and for designing your own pieces. Contents include an introduction; basics of the pop-up book; one piece techniques such as single slit and double slit; multi-piece techniques; designing your own pop-ups including single hearts, double hearts, and hearts with arrows; and a gallery. Also included is an index and acknowledgements. Fully illustrated with detailed step-by-step instructions for each project."
