Choose invitations that actually look inviting. Thick, high quality paper with bright colors or a unique design that makes the envelope stand out from other mail that may arrive on the same day. Your invitations should excite interest even before they are opened, and if you have chosen your design well, they should evoke reminders of the happy couple as well!
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.
