Going on record, account penned by non-drinkers is woolly stuff (6)
I believe the answer is:
alpaca
'woolly stuff' is the definition.
'alpaca' can be an answer for 'stuff' (alpaca is a kind of stuff). I am not sure about the 'woolly' bit.
'going on record account penned by non-drinkers' is the wordplay.
'going on' means one lot of letters go next to another.
'record' becomes 'LP' (abbreviation for long play record).
'account' becomes 'ac' (abbreviation for account).
'penned by' means one lot of letters goes inside another.
'non-drinkers' becomes 'aa' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'lp' next to 'ac' is 'lpac'.
'lpac' placed into 'aa' is 'ALPACA'.
'is' is the link.
Can you help me to learn more?
(Other definitions for alpaca that I've seen before include "S American mammal related to the llama" , "Andean beast of burden" , "Silky fleece of a lama" , "Fabric from wool of S American llama" , "Llama relation" .)
