Wife putting on fleecy layer (7)

I believe the answer is:

wadding

'fleecy layer' is the definition.
(thick material creating a fleecy layer)

'wife putting on' is the wordplay.
'wife' becomes 'w' (abbreviation).
'putting on' becomes 'adding' (I've seen this in another clue).
'w'+'adding'='WADDING'

I've seen this clue in The Times.
