Barring a themed wedding, chances are there is something unique about it, perhaps your wedding color. You can bring the colors of your wedding party into your invitations, although you do not want to just send out white and teal green invitations. Choose an interesting designed or textured paper in teal green and off set it with a sheer cover in cream. The best thing to do when using wedding colors for your invitations is to step out of the box and use your imagination.
There are also many options for mix and match wedding invitations. These are often sets of invitations that have many different options available for each of the pieces of your invitation set, from invitation paper to envelopes, fonts and scripts and more. By hand selecting these choices, you can create an individualized look to your invitations that speaks of the two of you as a couple without having identical invites that someone else has.
