Quilt square (5)
I believe the answer is:
patch
'quilt square' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for patch that I've seen before include "Piece of material used to cover hole in clothes" , "Repair; area" , "Covering material" , "Mend with piece of material" , "Piece of cloth put on another" .)
