Hi everyone! We are having our wedding in September, and have about 15 people going (so far). We are from Louisiana. We have told all of our close friends/family when the date is and that they are welcome. Unfortunately, of course everyone can't make the trip. I don't want to do formal invites, but what would be a good idea here? Should we do save the dates or something else? Should we send this to all of our friends/family or just the people that we know are coming? Thanks in advance!!!
