Want the polished look of professionally printed invitations without the high price tag? Stick to simple postcards, which are much more affordable than traditional cards and envelopes. You'll save money on printing costs and postage, and you won't have to stuff hundreds of envelopes.
Use your favorite picture of the two of you, or pick a simple wedding-related image for the front of the card. A sticker-making machine allows you to fasten pretty fabrics or vintage postcards to the invitation in lieu of an image. Print the basic details about your wedding on the card, and include a link to your Web site so guests can RSVP.
