Red rose embroidered for church screen (7)
I believe the answer is:
reredos
'church screen' is the definition.
(I've seen this before)
'red rose embroidered' is the wordplay.
'embroidered' is an anagram indicator.
'red'+'rose'='redrose'
'redrose' is an anagram of 'REREDOS'.
'for' acts as a link.
(Other definitions for reredos that I've seen before include "Back of fireplace" , "Hanging in church" , "Painted screen behind an altar" , "Church feature" , "Ornamental screen behind a church altar" .)
