Fold 30 origami vehicles, from intermediate to complex level, with many models featuring a color change.In this book, some traditional models will be re-introduced and new models, which are of my own design and one of Harri Thaha's model, will be introduced. The origami models in this book are from simple to complex models. The requirement of the type of papers on each model is different. Some models will be difficult to make with ordinary origami paper and require thinner paper (Some origamists 'make' their own paper for this purpose).
