Love to work with one material (5)
I believe the answer is:
voile
'material' is the definition.
(voile is a kind of material)
'love to work with one' is the wordplay.
'to work with' is an anagram indicator (letters worked into a new order).
'one' becomes 'i' (Roman numeral).
'love' anagrammed with 'i' gives 'VOILE'.
(Other definitions for voile that I've seen before include "Light semi-transparent fabric" , "Sheer fabric" , "fine material" .)
