Because of our environmental mission of reducing paper use and conserving trees, we do not offer inside envelopes. These guidelines are to help you address the one invitation envelope. Both informal and formal suggestions are given:

SINGLE PEOPLE:

Unmarried Woman	Shannon Harper and Guest/Ms. Shannon Harper and Guest *Of course, if your guest has a partner, please use his or her name on the envelope. "and Guest" is only for your guests who don't have mates, and you don't know who they might show up with!
Unmarried/Divorced Man	Perry Woods and Guest/Mr.Perry Woods and Guest*
Divorced Woman	Jesse Martinez and Guest/Ms. Jesse Martinez and Guest*
Widowed Woman	Martha Brooks and Guest (if enough time has passed)/Mrs. Martha Brooks (and Guest)

MARRIED COUPLES:

Married, same last name	Michael and Jane Harper/Mr. Michael and Mrs. Jane Harper *Keep in mind that depending upon envelope size and name lengths, including both the husband and wife's name on one line MIGHT mean giving up the titles.
Married, different last name	Jane Wilson and Michael Harper/Ms.(or Mrs.) Jane Wilson and Mr. Michael Harper
Married, woman has hypenated name	Jane Wilson-Harper and Michael Harper/Ms.(or Mrs.) Jane Wilson-Harper and Mr. Michael Harper
Married, both are doctors	Mary and Mark Connelly/The Doctors Connelly/Doctor Mary Connelly and Doctor Mark Connelly

Ms.Casey Phillips

SAME SEX COUPLE LIVING TOGETHER:

Michael Harper and Perry Woods

Mr. Michael Harper
Mr. Perry Woods

(On 2 lines, alphabetically by last name, if you know them equally well/or person you know the best on line 1, followed by partner on line 2.)

CHILDREN:

Multiple Children	Michael and Jane Harper Kerry, Todd, and Julie Mr. and Mrs. Michael and Jane Harper Kerry, Todd, and Julie Harper (It's not acceptable to use "and Family" if children are invited. List all of their names on the second line, underneath parents' names, from oldest to youngest, with or without the last name--sometimes this is decided by the amount of room on the envelope!) Another practical reason for not using the phrase "and Family" is that it is not clear exactly who is invited. Many customers with larger extended families report that having an open invitation to "and Family" could mean that a live-in parents, cousins, etc. might come along for the ride.
One Girl Child, under 18	Michael and Jane Harper and Kerry Mr. and Mrs. Michael and Jane Harper Miss Kerry Harper Mr. and Mrs. Michael and Jane Harper Kerry Harper
One Boy Child, under 18	Michael and Jane Harper and Todd Mr. and Mrs. Michael and Jane Harper Todd Harper
