On the underside of the wewene, dark overlaind strips of baan ni kaina are arranged in a series of small squares and a central horizontal band of triangular shapes across the wewene. In the initial preparation of the baan ni kaina, when the leaves are harvested as young green leaves, they produce the golden yellow colour. The two long edges of this wewene have been woven in a serrated pattern called wii n bakoa, named for shark teeth.
