Decorate from top to bottom or bottom to top (7)
I believe the answer is:
repaper
I believe this is a double definition.
'decorate' is the first definition.
(I've seen this before)
'from top to bottom or bottom to top' is the second definition.
(Other definitions for repaper that I've seen before include "renew wall-covering" , "Decorate again (palindrome)" , "Cover walls again" , "Decorate walls again" , "Apply new wall covering" .)
