Unkashū
Unkashū is a Japanese pattern book of cloud motifs compiled by Furuya Kōrin and published in Kyoto by Yamada Unsōdō in 1903, meant for artists and craftsmen seeking decorative designs. Its double-page spreads show rows of black-line cloud forms, from curling scrolls and swirling wisps to cumulus clusters and tree-like shapes, each drawn with clean, even outlines on plain paper that a designer could adapt as stylised motifs.
