Short family member with Chandler evens out rich material (7)
I believe the answer is:
brocade
'rich material' is the definition.
(I've seen this before)
'short family member with chandler evens out' is the wordplay.
'short family member' becomes 'bro' (I can't explain this - if you can you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'evens out' means one should take alternating letters (remove letters in even-numbered positions).
The alternating letters of 'chandler' are 'cade'.
'bro'+'cade'='BROCADE'
Can you help me to learn more?
(Other definitions for brocade that I've seen before include "Heavy silk fabric with a raised design" , "Rich woven fabric" , "Fabric woven with raised patterns" , "Richly-woven fabric" , "Rich fabric with raised patterns" .)
