The history of flower vines begins with arabesque patterns. Originally based on designs found in ancient Greek temples, they spread from Mesopotamia and Egypt to Europe, China, and other places. They were then domesticated in Japan via the Silk Road, giving rise to the flower arabesque. Because they grow quickly, they continue to be used today as a symbol of unbroken bonds, prosperity, and longevity. Willow trees also protect from wind and rain, and are believed to ward off evil. The appearance of frogs also symbolizes the coming of clear skies and abundance. This envelope set is crafted using the finest Japanese paper, showcasing its texture.
