Make sure to not crowd the card by only listing top priority points on the wedding invitation. These points include the time, place, hosts, names of the bride and groom, and RSVP details. If you want, you can also include the dress code for the ceremony, but you do not have to. When you try to put too much information on the invitation, it can get hard to read and look chaotic. Make sure to never list gift registry information on your wedding invitations. This bit of info should only ever be listed on your wedding website. It is not respectable to put these sort of details on your invites under any circumstance.
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.
