POST IT (notas adhesivas)

I want to recover my post its in Mac OSX. Anyone knows where does the notes are kept? I thought that backing up just the application was enough to save them and now I cannot see them, anyway to bring them back? From library or documents?

Thx

I don't know if this could be helpful, it's a 2004 MacDevCenter article... Anyway here's the link: Modifying Stickies. In it they show where the Stickies database is located.
