help...anybody?

I worked hard to come up with the design of both the background and the header, thanks to tips from The Cutest Blog on the Block.

As you can see the header is not centered. I've tried everything! I went to "edit html" and played with the margins and everything I could think of. I'm wondering if it may be my background, but I even tried messing around with it.

Does anybody have any suggestions?

Please.

I'd leave it, but it's the whole "order"...anal retentive need to have things just so.
