Someone posted a picture of their blunt rolled from printer paper once...I think it may have been Orangeman? Can't recall, but it cracked me up.

So I guess you can add printer paper to the list.

I've also heard of bible pages being used, but if your over-religious use the blank pages in the back.

Also the classic gum wrapper,which happened to be my first experience in rolling. Just remove the foil (as if you didn't already know).
