Making paper airplanes doesn't feel like science. We present step-by-step instructions for folding aerobatic amazement's. The ten airplanes in this book are the best we've ever seen. This big (10" x 12") book comes complete with 40 sheets of flight-tested, ready-to-fold paper. Printed on both sides is a variety of 20 colorful patterns, including leopard print, wood grain, hot rod flames and lose-it-on-the-lawn grass. It's everything you need to rule the skies.
