Playing with Hieu Dang’s money Ryujin, I decided to try and fold it money-size, but with fewer bits of paper:
I measured a korean dong note, then cut bits of paper 3×1, 2.5×1, 2.5×1 (body segments) and 3 note sized bits (head, 2xlegs) and set to folding.
The scale was tiny, it took about 3 weeks on and off and the result is lovely. With the Hanji ryu it is like a perfect pair – I imagine the larger is the female, the smaller spotty one is the male.
I _may_ attempt a satoshi Kamiya Ryujin 2.1, we shall see.
