This book offers a practical and clear-cut beginners guide to the basics of paper engineering. It begins by explaining the foundational techniques, and goes on to show the reader how to apply them in creative and fun ways by trying different variations and combinations to achieve an endless array of pop-up designs both simple and complex. Seven element spreads are broken down into different types of folds and mechanisms. Each spread demonstrates these elements and instructs the reader on how to construct the examples, which are designed to show the variations of the fold type or mechanic. Each of the seven element spreads has two detachable sections of card that can be removed by tearing carefully along the perforated edge and then pushing out the separate parts. Instructions on the accompanying pages explain how to construct the pop-ups and show how each element works.
