Fabric I mend somehow (5)
I believe the answer is:
denim
'fabric' is the definition.
(I know that denim is a type of fabric)
'i mend somehow' is the wordplay.
'somehow' indicates an anagram.
'i'+'mend'='imend'
'imend' is an anagram of 'DENIM'.
(Other definitions for denim that I've seen before include "maker of jeans" , "Twill cloth" , "Thick cotton cloth" , "Hard-wearing blue fabric" , "Twilled cotton fabric" .)
