Fabric whose reversal's no problem? (6)

Ross

I believe the answer is:

muslin

'fabric' is the definition.
(muslin is a kind of fabric)

'reversal's no problem?' is the wordplay.
'reversal's' shows that the letters should be reversed in order (I've seen 'reversal' mean this).
'no' becomes 'nil' (nil can mean zero or none).
'problem?' becomes 'sum' (arithmetic problem).
'nil'+'sum'='nilsum'
'nilsum' reversed gives 'MUSLIN'.

'whose' is the link.

(Other definitions for muslin that I've seen before include "Gauze-like cloth" , "Cotton for veil or strainer" , "Lightweight cotton cloth" , "dress material" , "Lightweight cotton fabric" .)

I've seen this clue in The Guardian.
