Woven by hand in Bolgatanga, northern Ghana, Africa, from hand-split and hand-twisted elephant grass. As these hats are handmade, some slight variations in size and colour occur. Trade Aid Integrated, WFTO.
To reform any "dents" in your hat, moisten (in the shower for 30 seconds, or dipped in water) and then reshape.
There are some great videos on how to reform hats. Watch here.
