Amir, I go prepared for paper art (7)
I believe the answer is:
origami
'for paper art' is the definition.
(I've seen this in another clue)
'amir i go prepared' is the wordplay.
'prepared' is an anagram indicator.
'amir'+'i'+'go'='amirigo'
'amirigo' with letters rearranged gives 'ORIGAMI'.
(Other definitions for origami that I've seen before include "Making of paper shape" , "Art of crafting objects from paper" , "Creation of objects from paper" , "Japanese paper-folding art" , "Art originally created in simple materials to design bird forms" .)
