Material supplied by dainty little daughter (5)
I believe the answer is:
tweed
'material' is the definition.
(I know that tweed is a type of material)
'supplied by dainty little daughter' is the wordplay.
'supplied by' says to put letters next to each other.
'dainty' becomes 'twee' (synonyms).
'little' says to take the initial letters.
The first letter of 'daughter' is 'd'.
'twee' put next to 'd' is 'TWEED'.
(Other definitions for tweed that I've seen before include "Twilled cloth" , "rough stuff" , "See 7" , "Scottish and English river" , "Running water" .)
