All of our woven bowls are created from dyed natural sisal fibers woven over a core of forest grasses. The weavers begin in the middle of the bowl, carefully threading the sisal around and around to create this beautiful design. The tea color is created when the naturally-white sisal fibers are steeped in Rwandan-grown tea leaves!
