A paperfolding paradise
The website of writer and paperfolding designer David Mitchell
|Division into Thirds and Fifths|
page attempts to record what is known about the origin

make such a division. 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.
