Japanese Crepe Paper Books
from The Baika Women's University Collection of Crêpe Paper Books in Japan (via flickr and BibliOdyssey)
...more than one hundred and fifty works produced between about 1880 and 1940 in English, Spanish, French, German and Portuguese editions.
Lightly moistened Japanese paper was wrapped around a vertical cylindrical form and crinkled by pressing the paper down to the bottom of the cylinder. The crinkled paper was removed, opened, and wrapped around the cylinder again in a different direction. This was repeated eight or ten times. By this laborious method, soft, crêpe-like paper was finally produced. In the process, the size of the Japanese paper was reduced to about 80%. The pages were assembled and bound with silk thread.
