Very delicate material provides comfort (6)
I believe the answer is:
solace
'comfort' is the definition.
(I know that solace is a type of comfort)
'very delicate material' is the wordplay.
'very' becomes 'so' (both can mean 'extremely').
'delicate material' becomes 'lace' (I've seen this before).
'so'+'lace'='SOLACE'
'provides' is the link.
(Other definitions for solace that I've seen before include "Comfort in time of disappointment or sorrow" , "Kind of comfort - a close thing" , "console" , "Relief in affliction" , "amusement" .)
