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.
Textures. You may not think so, but texture is an important aspect of your wedding invitations. Remember, texture is anything you can feel with your skin, and in this case, with your hands. If you can, use embossed or textured paper as a backing. This can add so much dimension and beauty to your wedding invitation. Balance. In art, balance refers to how "heavy" one side of the artwork is to the other. You should use the same concept in your DIY wedding cards.
