Stretching green mantle is out of order (11)

Ross

I believe the answer is:

enlargement

'stretching' is the definition.
(thesaurus)

'green mantle is out of order' is the wordplay.
'is out of order' indicates anagramming the letters.
'green'+'mantle'='greenmantle'
'greenmantle' is an anagram of 'ENLARGEMENT'.

(Other definitions for enlargement that I've seen before include "Photographic blow-up" , "Bigger version of photographic print" , "increase" , "Blown-up picture" , "Blown-up photo" .)

I've seen this clue in The Guardian.
