Hi ladies I have finished my STD's. I did them myself. so I need to send them out but my FMIL has made comments that even if the STD's are informal the addressing shouldn't be. I addressed one envelope for my parents since they live 1000miles away and it said "Mom and Dad" with the address. I have never sent them mail any other way. They know the date I just wanted to send them my project cuz I am so proud of them. How formal do I have to address them? My family knows me and if this is a problem should I just have her address the envelopes for the groom's side of the family so they are done to her taste. Now remember these are the save the dates not the invitations. TIA and sorry so long.
