Honestly, I’d consider skipping the Mr. and Mrs./Ms. and just go with first and last names - James & Amanda Williams. But I’m not big on formality especially when it is a personal event like a wedding where one likely knows the majority of guests well. But I’m sure you’ve suggested all the practical options…
We used clear Avery labels. We were able to choose the font, and could have more than three rows. We had a couple of:
Mr. James Williams
Mrs. Amanda Williams
1234 Their Street
City, State 00000
So…@intparent can she put each person’s name on a separate row?
We used a font that matched the invitations. I just sent DD a set of the labels she can use for her thank you notes.
I thought they looked nice enough.
The two lines are really fine.
And if you want to skip the Mr & Mrs title implications, think about not always making the male name the first, whether one line or two. (Right? 
)
She has recovered her equilibrium. 
Ended up with a variety of addressing styles depending on the length of names & who was getting them.
That’s what my D did: she used the more formal (“etiquette-correct”) format for those who would prefer that (…mostly us oldsters) and “James and Amanda Williams” for those who didn’t… plus a few two-liners, too.
My S and DIL also had their envelopes addressed by the company that produced their invitations. Due to some snafus, I ended up stuffing and mailing the invitations and I can tell you the format for the names varied from the most formal to the most casual. I think they pretty much use @scout59 D’s approach - formal for the older generation ( Mr. and Mrs.) and casual to the point of ridiculous for some of their friends (Mike & Molly - no last names). Since they sent a spreadsheet of the names/addresses to the company, they were able to do this easily. I suspect the bride’s mother would have been mortified, but for reasons beyond her control, she never saw the addressed envelopes.
My daughter and her then-fiance used “Amanda and James Williams” or, in those instances where the husband and wife (or the two SOs) do not use the same last name, “Amanda Smith and James Williams.” Nobody seemed to object.
H’s cousin used the less formal “Amanda and James Williams” when she addressed her invitations a few years back. Their aunt had a complete fit about it, and it created a huge rift in the family. My in laws got stuck with the aunt & her H at the reception - no one ever came to talk to them the entire night. My D made sure to address the envelope to “Mr. and Mrs. James Williams” for that couple to keep the family peace.
Seriously, people. What a dumb thing to get upset over!!
Just read the Why is it little things that push you over the edge thread. There are no dumb things when planning a wedding. I was pushed over the edge when the flowers for the welcome party didn’t show up on time. For D1 is was when she found out we had drive an hour to get the marriage license.
@kelsmom D asked me to look them over tonight to see if what she has decided on looks okay. Mostly we need to make sure that Grandpa’s looks formal, I think.
Brides and MOBs are allowed to get pushed over the edge at least one or twice when pulling off a wedding. . Guests, especially on how their invitation is worded, are not.
Maybe no one talked to the complaining aunt and uncle because, well, they are the complaining aunt and uncle. I doubt the invitation was the only thing they had an opinion about.
We are on wedding invitations this week. My d addressed the envelopes by hand in calligraphy. She found it it a stress reliever when studying. The last envelopes will be shipped to me when finals are over. She is going for formal wording- her choice.
My good friend printed the invites in letter press. I think it was a lot more work than she anticipated. I love the final result- though I’m sure it aged her 5 years. She had a couple of misses- huge learning curve. I’m assembling the package this week complete with belly bands etc. She had fun with a “cricket” machine putting the finishing touches together. The liners are a pain to insert in the envelopes. The invite would have been well out of our budget had she not offered to do them. What a beautiful gift to my daughter!
@Sally22 Is your friend in the printing business with letterpress machine and all?
That is a nice gift!
Dd’s MIL made her invitations too…and we loved them. Agreed, what a wonderful and meaningful gift.
@doschicos in our case, the MIL had a friend who did all the printing…but MIL had everything else…cricket, embosser, etc.
And very nicely a couple of guests at our DD’s wedding have already contracted with her to do their wedding invites!
no- just an eager amateur. She rented studio time at a printers.
Even more impressive.
@travelnut - how did the wedding go? I am sure it was wonderful.
Thanks for asking, @oldfort. It was an amazing weekend. Just coming up for air; will give more details tomorrow.
What’s a cricket?
