Queen allowed to wear embroidered felt, soft fabric (11)
I believe the answer is:
flannelette
'soft fabric' is the definition.
'flannelette' can be an answer for 'fabric' (flannelette is a kind of fabric). I am not sure about the 'soft' bit.
'queen allowed to wear embroidered felt' is the wordplay.
'queen' becomes 'anne' (I've seen this before).
'allowed' becomes 'let' (I've seen this before).
'to wear' indicates putting letters inside (to wear something is to be covered up by it).
'embroidered' is an anagram indicator.
'anne'+'let'='annelet'
'felt' anagrammed gives 'flte'.
'annelet' inserted within 'flte' is 'FLANNELETTE'.
Can you help me to learn more?
(Other definitions for flannelette that I've seen before include "Cloth made from cotton" , "Cotton imitation of a light woollen fabric" , "Napped cotton fabric" .)
