Kapu Bafi describes hand woven sphere-like objects that may have lids. It is done by weaving leaflets of palm trees around a special kind of straw-like object called ‘Kertak’, which is a wild plant that grows in swamps and tropic climates.
Kapu are woven by the masterful hands of women of Khuzestan and all of its material are natural and found in lands of this province.
During recent years, the weavers have begun incorporating colorful woolen in their Kapu to add to the beauty of their products. Palm tree leaflets that are chosen to be woven into Kapu are young and white because they have not been exposed to sun for a long time. They are then soaked in water for a day.
The Kapus are also made into different utensils such as vases, coasters, fruit bowl etc. Dezful and its surrounding villages like Shahyun are the most important centers of Kapu.
Since the core fibers of Kapu, the Kertak, are sensitive to humidity, they are best kept in dry conditions.
