Do particularly well as pattern-maker (3,2,7)
I believe the answer is:
set an example
'particularly well as pattern-maker' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'do' is the wordplay.
I cannot really see how this works, but
'do' could be 'set' (synonyms) and 'set' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for set an example that I've seen before include "Act well so that others may copy" , "Behave as a role model should" .)
