Biriko - women's symbol and a dancing fan
There are two kinds of Biriko . The largest is used as a versatile everyday item: as an adult sleeping mat, to cover babies and sleeping toddlers for protection, as an umbrella to protect from rain or sun, as a covering for food knapsacks, and for wrapping and storing food during a journey. The utility and beauty of its design make it a valuable trade item or compensation payment.
The small Biriko is used mainly for dancing during feasting occasions. It takes skill to make the Biriko and there are traditional patterns such as "sago seed" or "grasshopper's legs" designs. It is made by sewing together four leaves of a young palm tree with string made from tree vines. The large Biriko is made from a more mature palm. It is double the thickness and on one side a slit is left open to create a pocket in between.
