I have a huge family... My mom wants me to invite some of my close cousins. I'm not sure exactly what etiquette is. For instance, she wants me to invite my aunt and uncle-- and their three kids (21, 18 and 15). Do I write seperate invites for the older kids? While the wedding is small, they will be allowed to invite a guest, (Especially since my 18 year old cousin is dating a guy that's related to me on the other side of my family. lol) Thanks!
