The Full Block business letter layout is the easiest to format. Here everything starts at the left margin, and Dixie delights in the fact that no tabs are needed. This style is efficient and businesslike. No wonder it has become so popular and it is Dixie's first choice, too. Don't you just like the way it looks?!
Each of business letter layouts merits its own page, so go to the Full Block Business Letter page to read about it in more detail and also to see a list of major elements of a business letter.
Dixie thought that she needed to mention though that some critics feel that this layout looks a little crowded. Well... it's good then that there are two more of them, modified and indented.
