Work on some other material (8)
I believe the answer is:
applique
'work' is the definition.
(I have seen 'Ornamental work ' mean 'applique' so perhaps 'work' could also mean 'applique')
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for applique that I've seen before include "Ornamental needlework" , "Style of needlework" , "Practice of sewing pieces of decorative material together" , "Sewn-on decorative trimming" , "Decorative design made of one material sewn over another" .)
