Nailed by judge, a blighter hanging (8)
I believe the answer is:
tapestry
'hanging' is the definition.
(I know that tapestry is a type of hanging)
'nailed by judge a blighter' is the wordplay.
'nailed by' means one lot of letters goes inside another.
'judge' becomes 'try' (as in trialling a defendant).
'blighter' becomes 'pest' (synonyms).
'a'+'pest'='apest'
'try' placed around 'apest' is 'TAPESTRY'.
(Other definitions for tapestry that I've seen before include "Fabric picture" , "Heavy fabric wall-hanging" , "a picture on the wall" , "Woven hanging fabric with pictures" , "Woven wall-hanging" .)
