Default Formatting In Microsoft Office 2007 (Word)?

I am having trouble changing the default formatting for blank documents in Microsoft Word 2007. I hate having to change it every time (as the factory default is Calibri, 11 pt, double spaced), but cannot seem to change the default settings. I've tried creating a Quick Style then clicking Change Styles>>Set As Default, but this seems to have no effect on the default formatting. Has anyone successfully changed their default, and how? (Please Be Specific, Thanks!)

To do this, click the Microsoft Office Button, click New in the New Document task pane, click Blank Document, and then click Create.

In the Font group, click Fonts.

Select the font, the point size, and any attributes that you want in the Fonts dialog box.

Click Default.

Click Yes when you receive the following message:
Do you want to change the default font to font name?
This change will affect all new documents based on the NORMAL template.

Click OK.

Click the Microsoft Office Button, and then click Word Options.

In the Customize tab, select Commands Not in the Ribbon in the list, and then select Save All.

Click Add, click OK, and then click Save All in the customized Quick Access Toolbar.

Note If Word prompts you to save the new blank document, click Cancel. If you want Word to prompt you to save the changes to the Normal template, follow these steps:

Click the Microsoft Office Button, and then click Word Options.

In the Advanced tab, click to select the Prompt before saving Normal template check box in the Save group.
