Martin, To be absolutly correct you would need to say, `ON ONE SIDE` of a sheet of paper. As your link shows, it can be done, but you would need to use both sides.
Splitting hairs - I know. But it could be an important point if a £100 bet rested on the outcome.

I really like this site - It`s now in my `favourites` folder.
