Elaborate, embellish (9)
I believe the answer is:
embroider
I believe this is a double definition.
'elaborate' is the first definition.
(I've seen this before)
'embellish' is the second definition.
(I know that embellish can be written as embroider)
(Other definitions for embroider that I've seen before include "Embellish (with needlework?)" , "Elaborate" , "stitch" , "Sew; embellish" , "Sew decoration onto" .)
