Award for painting and wallpapering (10)
I believe the answer is:
decoration
'award' is the definition.
(I know that decoration is a type of award)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for decoration that I've seen before include "New Year's honour, say" , "Adornment - medal" , "Flags put out" , "Bunting (in honour of a brave man?)" , "award" .)
