this one is a single page made into a book, without glue (well, it works better with a few tiny bits).
I have made 3 which you’ll see below and in the videos, and I suspect I’ll make a few more.
I’ve learnt that lighter weight paper is better – 100 gsm was too thick, and even 90 gsm was too. but I can probably adjust the folds. they suggest 90 gsm / japanese paper in the hedi kyle art of the fold book
