Corded cloth isn’t commonly to change colour (7)
I believe the answer is:
repaint
'change colour' is the definition.
'corded cloth isn't commonly' is the wordplay.
'corded cloth' becomes 'rep' (I've seen this before).
'isn't commonly' becomes 'ain't' (I've seen this in another clue).
'rep'+'aint'='REPAINT'
'to' acts as a link.
(Other definitions for repaint that I've seen before include "put on new coat" , "To provide fresh cover" , "put on another coat" .)
