Sails fashioned from plant material (5)
I believe the answer is:
sisal
'plant material' is the definition.
'sails fashioned' is the wordplay.
'fashioned' indicates an anagram.
'sails' with letters rearranged gives 'SISAL'.
'from' acts as a link.
(Other definitions for sisal that I've seen before include "constituent of rope" , "Type of fibre" , "Sails (anag) - fibre" , "Strong rope fibre" , "Ropemaker" .)
