You also have several templates to choose from with Open Office software, but Microsoft Word provides a wider selection. However, if you do find a template that seems good enough and you'd like to customize it, go to Wordlabel.com to download the file. To open it, right click Open With and then select the software. You can then modify it however you want.
You can align your logo by clicking any of the alignment buttons at the menu bar. Press the 'Enter' key on your keyboard and you can type in your business address or a slogan. You can format the text just as you would when you're creating a MS Word document. You can choose the font, font size, color, align the text and even add graphic lines.
