Browsing the internet, as you do, I came upon a chance find of an amazing archive of pages from what is thought to be the oldest Origami book published – “Hiden Senbazuru Orikata (The Secret of One Thousand Cranes Origami)”, first published in 1797:

Looks like i have a new project, making Tsuru (traditional Cranes) in multiples on a single (cut) sheet – looks like it is going to be a fascinating ride.

I present my version 1 of a “Double Tsuru”, joined at the beak, as opposed to the original illustration which joins them at the wing/hip

More to come, interesting puzzles these, working out how to do it without fatiguing the paper to breaking point – gently, gently.
