Large amount of clubs needing creative work pack (8)
I believe the answer is:
cartload
'large amount' is the definition.
(a cartload of something is a large amount of it)
'clubs needing creative work pack' is the wordplay.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'needing' says to put letters next to each other.
'creative work' becomes 'art' (artwork).
'pack' becomes 'load' (loading is a kind of packing).
'c'+'art'+'load'='CARTLOAD'
'of' acts as a link.
(Other definitions for cartload that I've seen before include "large quantity in vehicle" , "Enough for a horse to pull" .)
