Most traditional origami is done using a single square sheet of paper however certain models require that rectangular sheets of paper with certain proportions are used.

Because the paper money of different countries are all different sizes this gives you a bunch of differently shaped rectangles to fold origami out of while also giving you constraints when you try to design models.

There’s actually been a lot of origami made from folding paper money and the different colours used on the bills from different countries can also give the finished piece a colourful and unique look that you wouldn’t normally see with regular origami paper.

Alexandr Pak has designed a couple of great origami trees using paper money.
