Turn to corner to fix things (3-3)
I believe the answer is:
dog-ear
'turn to corner' is the definition.
(as in dog-earing a page in a book)
'fix things' is the wordplay.
'fix' becomes 'do' (I've seen this in other clues).
'things' becomes 'gear' (gear can mean supplies or equipment).
'do'+'gear'='DOG-EAR'
'to' is the link.
(Other definitions for dog-ear that I've seen before include "Corner of a page turned down to mark your place" , "Crease in book page like canine appendage" , "Hint of shabbiness" , "Fold down a corner (of a page)" , "Fold on page's corner" .)
