Daughter needs a face-covering material (6)
I believe the answer is:
damask
'material' is the definition.
(damask is a kind of material)
'daughter needs a face-covering' is the wordplay.
'daughter' becomes 'd'.
'needs' means one lot of letters go next to another.
'face-covering' becomes 'mask' (I've seen this before).
'd'+'a'+'mask'='DAMASK'
(Other definitions for damask that I've seen before include "Fine linen with woven pattern" , "Lustrous cloth" , "Patterned material" , "Patterned table linen" , "Material, originally Syrian" .)
