The decision you and your fiancé have is only one of many when it comes to planning your wedding day. If you have planned a themed wedding, then a unique wedding invitation can be a little easier to come up with. Let your imagination go with the theme of your wedding and do not be afraid to step out of the box. If you are having a Hawaiian themed wedding, you could send out invitations to your guests that have images of luaus and Hawaiian flower leis.
Children are not invited to the wedding: This is very difficult indeed and again should not be mentioned on the invitation. Invitees should actually realise that if their children aren't mentioned by name on the invitation then they're not invited but they probably won't. Friends of the bride and groom may not appreciate that you don't look on their little darlings quite as they do but be firm. Friends with children should be telephoned and politely told that children cannot be catered for. If they are offended, then that's unfortunate.
