Become fond of job making carpet (4,2,4)
I believe the answer is:
take to task
'carpet' is the definition.
(I've seen this before)
'become fond of job' is the wordplay.
'become fond of' becomes 'take to' (I've seen this before).
'job' becomes 'task' (synonyms).
'taketo'+'task'='TAKE TO TASK'
'making' is the link.
(Other definitions for take to task that I've seen before include "form a liking for the job" , "Give a rocket" , "rebuke" , "give worker a lift in" , "censure" .)
