Personally I like to place my business address at the bottom of the page or the footer. To do this go to the floating bar and click on the button, 'Switch Between Header and Footer.' This will open a dotted box at the bottom of the document. You can type your office address here or anything you see fit for your letterhead. Again you can format the text by choosing the font, font size, color, align the text, etc.
Creating Labels _ Another good use of Microsoft Word is creating labels. It is designed with pre_defined templates that allow you to create labels and customize them according to specific measurements to fit your label's dimensions. There is also an available wizard that guides you through the process of creation through printing.
