Hi there Beverly and welcome
You can use Wordpad for this
Click start, type in wordpad and press enter
This will open up and you can then use this to write your letters
To change the type of paper, click File, Page Layout and you can choose the different page sizes there
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
