Publicity material with alternative directions for ornaments (6)
I believe the answer is:
adorns
'for ornaments' is the definition.
('adorn' can be a synonym of 'ornament')
'publicity material with alternative directions' is the wordplay.
'publicity material' becomes 'ad' (short for advert).
'with' means one lot of letters go next to another.
'alternative' becomes 'or'.
'directions' becomes 'ns' (N is an example).
'ad'+'or'+'ns'='ADORNS'
(Other definitions for adorns that I've seen before include "decks" , "Bedecks" , "Adds ornamentation" , "'Decorates, embellishes (6)'" , "Decorates with ornaments" .)
