So I have a somewhat technical question... I am addressing a STD to to my cousin and her husband and they both have formal titles that I know I need to use. I'm sure it doesn't matter so much for the STD since they are less formal but this is more for the invite in the future.
The problem is the formal titles are so long that if I wrote as small as possible to make their names fit on one line that it would not be legible. So my question is, is it okay to put his name/formal title on the first line, and "and" on the second line, and her name/formal title on the 3rd line?
