In 2008, Naoto Fukasawa designed a line of slippers, bags, and other accessories for Japanese paper manufacturer Onao. Called Siwa, which means "wrinkle," they’re made of crumpled Naoron, a soft but tear-resistant paper. "It reminded me of rolling up the opening of the brown bags I carried my sandwiches in when I lived in America," writes Fukasawa in his new book, Embodiment.
