I sell faulty material... (5)

Ross

I believe the answer is:

lisle

'material' is the definition.
(I know that lisle is a type of material)

'i sell faulty' is the wordplay.
'faulty' indicates anagramming the letters.
'i'+'sell'='isell'
'isell' anagrammed gives 'LISLE'.

(Other definitions for lisle that I've seen before include "Strong twisted cotton thread for the strange Ellis" , "(Fabric woven with) a fine cotton thread" , "Cotton stocking thread" , "Strong cotton fabric" , "Twisted yarn" .)

I've seen this clue in The Irish Independent.
