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.
Other color choices _ If you do not want to use your wedding colors on your invitation, you will probably want to stick with the more traditional ivory or white paper, with black or, for a more formal wedding, metallic ink. You can use these colors on your invitation and be perfectly proper, whether your wedding colors are bold or pastel, traditional or contemporary.
