A New Document
When you
saved your own business template, you were prompted to select the
Templates folder as a place to put it. Now, when you go to
Office -> New, you should see your business letter in My
Templates.
Double
click Charlotte's Business template and you will open a new
document. It should be formatted with a logo and many Quick Parts.
What Do
You See? Look at the Title Bar at the top of Microsoft
Word. Does it say: Document4? Here is the clue that you are working
on a new document which you can save if you wish.

Memo To Self: It may or may not say Document4
depending on how many other files you opened this time. ;-)
