Paper to do origami missing last two bits (5)
I believe the answer is:
folio
'paper' is the definition.
(folio is a kind of paper)
'do origami missing last two bits' is the wordplay.
'do origami' becomes 'fold' (origami involves folding paper).
'missing last' means to remove the last letter.
'two bits' becomes 'io' (1 and 0 are two bits in computing).
'fold' with its last letter removed is 'fol'.
'fol'+'io'='FOLIO'
'to' is the link.
(Other definitions for folio that I've seen before include "Book; wrapper for loose papers" , "outsize book" , "Sheet of paper folded to make two book leaves" , "Manuscript sheet" , "Two-leaf sheet" .)
