This Introductory Course to origami polygon packing method (box pleating) is a comprehensive yet easy to understand course, dedicated to one of the most advanced and the most-widely used method in origami today.

This course will give you a theoretical foundation needed for you to become a truly successful origami artist. To sum up: if you simply want to learn how to fold some pretty models that other people have designed, without getting a broader understanding of it, then this course is not for you.
But if you are ready to immerse yourself deeply into theory, if you are willing to put an extra effort to understand the idea behind origami and if you are not satisfied with repeating other people’s work without understanding how they’ve come up with such a design, then this course is ideal for you and I’m 100% positive you’ll love it.
