Back towards the end of May I posted a picture of a very tiny set of origami
that I made using bond paper and my fingers and the question was asked, “How do you make them?”
Apparently claiming magic is frowned upon by the Instructables community.
I believe the following instructable will help to answer your questions.
Folding small models is, in many ways similar to folding regular sized models. Really there are two main challenges to it. First is paper thickness. We take for granted that paper is..well...paper thn! It makes it easy to fold because it is thin relative to the overall size. Once we get down to small scales the ratio of paper thickness to paper width is much less generous. Add to that the fact that each time you fold over you double your thickness and this is like folding a phone book.
I was considering demonstrating this through an interpritave dance, but I went for the instructional video.
Part 1: I introduce some basic ideas and fold the first large model
