Then in the center of the envelope you put the person's fist and last name then below it their address then below that again... their city, state, and zip code!
You put his/her name and address.
* The males name appears first. Example: Mr. & Mrs. John Doe
Proper business etiquette dictates that the man should be first even with an informal envelope however many have used the woman's name first if she is more familiar to the sender. You address as the Man's name first. ei. Mr & Mrs Stephen Kariwiec
Forget using the attention line. Just put the persons name in the first line of the delivery address.
