This writer's put on fake leather (6)

I believe the answer is:

shammy

'leather' is the definition.
(shammy leather is a kind of leather)

'this writer's put on fake' is the wordplay.
'this writer' becomes 'my' (I've seen this in other clues**).
'put on' means one lot of letters go next to another.
'fake' becomes 'sham' ('sham' can be a synonym of 'fake').
'my' put after 'sham' is 'SHAMMY'.

(Another definition for shammy that I've seen is " Soft leather".)

I've seen this clue in The Guardian.
