Cooler to decorate with taste
I believe the answer is:
ice bag
'cooler' is the definition.
(thesaurus)
'decorate with taste' is the wordplay.
'decorate' becomes 'ice' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'taste' becomes 'bag' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ice'+'bag'='ICE-BAG'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for ice bag that I've seen before include "Big ace (anag.); cool carrier" , "cooler" , "Cold item applied to reduce swelling" , "cold compress" , "Waterproof container" .)
