Creating Envelopes _ Your letter will not be complete unless you have an envelope also formatted appropriately. What's good about this function is that you can either customize your own envelope or allow Word to come up with a matching envelope to the letter you have written using the application. What it does is it automatically copies the address and uses it to create the envelope. That helps you do away with manual typing.
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.
