The magnum opus of one of the world's leading origami artists, the second edition of 'Origami Design Secrets' reveals the underlying concepts of origami and how to create original origami designs. Containing step-by-step instructions for 26 models, this book is not just an origami cookbook or list of instructions - it introduces the fundamental building blocks of origami, building up to advanced methods such as the combination of uniaxial bases, the circle/river method and tree theory.
For those who are interested in the field - whether as art, for the fun of folding or the various potential practical applications - the best book on the subject by far is Robert Lang’s Origami Design Secrets[1], which is a fantastic read and covers all of these and more. Lang is a mathematician at heart but also a consummate artist. I certainly can’t recommend origami enough as a hobby.

For something that still touches on some of this stuff but is more beginner/child friendly, I'd recommend Jun Maekawa's book Genuine Origami (https://www.amazon.com/dp/4889962514)
There's also the OSME books (http://osme.info/) which collect origami related papers.
If you are a beginning designer, you should realize that no design is sacred. To learn to design, you must disregard reverence for another’s model, and be willing to pull it apart, fold it differently, change it and see the effects of your changes.
Small ideas lead to big ideas; the concepts of design build upon one another.
