The Sumi-A-Day Tumblr is an ongoing art project by artist collective Maternal Mitochondria. Every day, a new piece of suminagashi! Suminagashi is a Japanese printing technique that creates unique monotype prints using ink and water. Maternal Mitochondria uses both traditional and modern materials and techniques. Suminagashi is related to Western marbling and Ebru techniques, but brings it’s own artistic merits to the table.
