Tie design (4)
I believe the answer is:
draw
I believe this clue is a double definition.
'tie' is the first definition.
(I know that tie can be written as draw)
'design' is the second definition.
(I've seen this before)
(Other definitions for draw that I've seen before include "Tie - attract" , "Tied score; sketch" , "Finish level" , "attractive thing" , "Design" .)
