Knot in lace - it's stiff (9)

Ross

I believe the answer is:

'stiff' is the definition.
(I've seen this before)

'knot in lace it's' is the wordplay.
'knot' indicates anagramming the letters (I've seen 'knotted' mean this).
'in'+'lace'+'its'='inlaceits'
'inlaceits' is an anagram of 'INELASTIC'.

(Other definitions for inelastic that I've seen before include "Rigid", "unable to bend?", "Non-stretch", "Broken", "stiff".)

I've seen this clue in Sydney Morning Herald.
