Suminagashi is a traditional Japanese art form that involves creating beautiful patterns on water's surface using ink. The technique dates back to the 12th century and is often considered one of the earliest forms of marbling. Artists gently drop ink onto water, allowing it to spread and create intricate designs before transferring the patterns onto paper. The process of Suminagashi is simple yet requires a steady hand and a keen eye. Artists use special tools, such as brushes or bamboo sticks, to manipulate the ink and create unique shapes. The final result is a stunning piece of art that captures the fluidity and beauty of nature.
