On the other hand, if your unique wedding invitations are of a particularly unusual design, chosen to reflect your own personal style as well as the style of your wedding, your guests may know they can expect something nontraditional.
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.
