Query: 3 nice models and challenging easy to expert models too.

This was my first book too. However my 5 stars on this book is because Montroll's Stink Bug and the Grasshoper are, in my oppinion, pure origami and both a masterpiece.There are other models on this book which will teach you basics to create your own models in the future. Like eg. how to make four legs and separate parts of the paper for wings etc.Must have for sure. Enthusiasts ftw! ^^
