The Square Hat / Le Bonnet Carre
This page attempts to record what is known about the origin and history of the origami design known as Le Bonnet Carre. Please contact me if you know any of this information is incorrect or if you have any other information that should be added. Thank you.

Le Bonnet Carre appears to be a development of the Workman's Hat.


In Japan (and in publications by Japanese authors)


This design appears as both 'A Waste-paper Basket' and as 'A Hood' in 'Pocket Guide to Origami: Bow-Wow Book', by Isao Honda, which was published by the Asahi Origami Club, Tokyo in 1959.



This design appears, as the 'Waste-paper Basket', in 'The World of Origami' by Isao Honda, which was published in the USA by Japan Publications Trading Company in 1965.
