Basketry fiber (6)
I believe the answer is:
raffia
'basketry fiber' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for raffia that I've seen before include "Woven palm tree fibre" , "Type of palm tree" , "Fibre used for weaving mats, baskets, etc" , "Palm fibre for e.g. baskets" , "Palm leaves used in weaving" .)
