Curtain ornament (6)
I believe the answer is:
tassel
'curtain ornament' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tassel that I've seen before include "Hanger-on perhaps" , "Part of maize plant" , "Hanging bunch of cords" , "Grapefruit and tangerine hybrid" , "Ornamental hanging tuft" .)
