Re: History of the valley and mountain folding lines

I believe that the confusion regarding the origins of the notation system arise, in part, from the following sentence written by David Lister, which set the path to believe that Yoshizawa was the actual "creator" of the dash-dash and dash-dot-dash convention, when he certainly was not. "I have never...

Re: History of the valley and mountain folding lines

On July 2nd, 1952, Ligia Montoya (Argentine paperfolder) wrote one of her first letters to Gershon Legman. Accompanying this letter was a diagram of a seal which she reproduced by looking at a picture published in an article about Vicente Solórzano Sagredo (the seal was his creation). What's interes...

Re: History of the valley and mountain folding lines

I want to share with you an intriguing finding. Maybe not intriguing for you but for me it is. After buying the Neal Elias DVD by Dave Venables, and reading the introduction by David Lister to the work of NE, something rang in my mind and I went to the correspondence between Neal Elias and Gershon L...

Re: Mattia Giegher "Li tre trattati"

Thank you Joan for sharing your incredible amount of research work. You mention that Giegher taught at University of Padova. Is there a reference in the book about that or how did you find out?

Teaching geometry with paperfolding (Argentina- 1958)

In 1958 my sister was 8 years-old. She had to cut strips of paper and divide them in fractions (picture 1). Following are ...

I imagine you seeing yours unidentified Japanese book at page 28 and if you find a picture of the Chinese junk (on page 28), this book could be "Origami Moyo". Thanks Michel, yes, after I sent my reply y...

Thanks so much Michel! That's smart. I just ordered the book (1956 edition) from Abebooks. Can't wait to see what's on page 28.

Happy Holidays!

Origami Moyo

Hi everyone, I wonder if anyone of you has a copy and could send me or upload a picture of the cover of the books named Origami Moyo (two volumes), by Kodo Kawarasaki (1935). I may have that book but cannot identify it due to my ignorance of the Japanese. By now you may know that I own several of th...

Thanks Laura for giving us an occasion to read this original (in Italian)
Thank You, Michel G, since I posted I also found some more literature. There is also a short bio in Wiki, but no mention of that paper.
