Paragraphs written in a block style are ones with the first line flush with the left margin. Example The following paragraphs are written block style. There are many ways to format a letter or other text. One can indent the date and/or return address. One can indent the first line of every para- graph. One can indent the closing. If one doesn't indent any of these features of a business letter, then the letter is said to be written in a block style. When date, return address, and closing are aligned at the center (or a little right of center), the style is said to be "modified block style."
Block Paragraphing is simply a style of writing. They are paragraphs with no indentions. Use a 12 point font size. Center the main heading in bold 16 type font and 2.0 between each sentence.
