I fool about with some paper (5)
I believe the answer is:
folio
'some paper' is the definition.
(folio is a kind of paper)
'i fool about' is the wordplay.
'about' is an anagram indicator.
'i'+'fool'='ifool'
'ifool' with letters rearranged gives 'FOLIO'.
'with' acts as a link.
(Other definitions for folio that I've seen before include "Four pages" , "Leaf of paper" , "eaf" , "Sheet of paper folded to make two book leaves" , "Book made of folded sheets" .)
