Made bedspread black for queen (5)
I believe the answer is:
built
'made' is the definition.
(building is a kind of making)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for built that I've seen before include "assembled" , "Erected" , "put together" , "Made by combining materials and parts" , "Constructed" .)
