Little Big Planet - How do I save!!!

Okay so I just got it, I might have missed something or something but Im on the fourth level or so, and I dont ever recall the thing telling you how to save And on top of that, I cant find a save option, so how do I save?

Thanks

You dont have to. It has Auto-Save. Almost every game has.

Let me restate what the previous two have already restated. It auto-saves.
