Barcodes used for expensive fabrics (8)
I believe the answer is:
brocades
'expensive fabrics' is the definition.
'brocades' can be an answer for 'fabrics' (brocade is a kind of fabric). I'm unsure of the 'expensive' bit.
'barcodes used' is the wordplay.
'used' indicates an anagram.
'barcodes' is an anagram of 'BROCADES'.
'for' is the link.
Can you help me to learn more?
(Other definitions for brocades that I've seen before include "Weaves a raised design" , "Materials" .)
