Cautious repairs to fur and lace (7)
I believe the answer is:
careful
'cautious' is the definition.
(synonyms)
'repairs to fur and lace' is the wordplay.
'repairs' indicates an anagram (I've seen 'repaired' mean this).
'and' means one lot of letters go next to another.
'fur' after 'lace' is 'lacefur'.
'lacefur' anagrammed gives 'CAREFUL'.
(Other definitions for careful that I've seen before include "Diligent" , "Watch it!" , "Painstaking" , "Thrifty" , "'Prudent, cautious (7)'" .)
