Wedding Invitations - Details Invitations can be folded along the side or on the top. Flat invitations are also an option, printed on one side only, or double-sided. The choice of ink colors is virtually endless, so you can even use your wedding dress to develop the theme and style of your wedding invitations. Reply postcards are innovative and will save you the cost of printed envelopes. Just print the reply information on one side and your address on the back.
Guests can simply pop the reply card in the mail.
