The North Wosera bilum five category pieces are found among the South Abelam people scattered on the low hills of Sepik plains of Maprik, East Sepik Province. The two common features of colors and patterns and designs have distinct names in local dialect passed on to successive generations. The colors and pattern in layers and variations are distinct faetures in the common Sepik bilum. Few of these pieces are lost and need to be revived and preserved for future generations.
