What I Did:

Since this was an informal wedding, I made my own invitations. They were printed on a mottled grey cardstock. (Click the thumbnails below for larger views.)

Credit	The front was a black-and-white still from The Bride of Frankenstein, featuring a closeup of Frankenstein's monster and the Bride.
	The inside left was a poem by Dexter Kozen (a text copy is here, and it's also been set to music). The font used was "Ghost Town." (Note: The "broken" appearance of the lettering isn't due to a poor-quality image; Ghost Town looks like that.)
	The inside right was the invitation information. The fonts were "Halloweenies" wingdings, "Cloister Black," and "Oak."
	The back was blank, although I'd considered putting the small "Produced by" line at the bottom, specifically for amusement value (I put it inside instead).
Credit	I had wanted to use "Classic Movie Monsters" stamps on the envelopes, but the post office had unfortunately stopped issuing them. So I settled for their "Insects and Spiders" collection.
	Instead of an RSVP card and envelope, I included a small card directing them to a Website I'd created (Note: I've disabled some of the links on that site, since they were intended only for guests and not the public at large).

Other Suggestions:

• The illustrator Edward Gorey drew many things which could best be described as "Elegant Macabre." Some of his drawings might be used for a more formal printed invitation.

• Print your invitations, thank-you notes, programs, etc. on parchment in elegant Olde English and Gothic fonts. Seal the inner envelopes of your invitations with wax seals. Traditional sealing wax will often crack or shatter in the mail, so either hand-deliver these invitations or use "mailable" sealing wax. Many companies also offer "peel seals"--plastic seals that look like wax--in a design of your choice.

• Look for old-fashioned Halloween cards; there are some particularly nice Victorian ones. If you don't want to hand-write your information, print it on pretty paper and insert it and a little Halloween-shaped confetti in the card.

• If you're inviting a small group of people (or don't mind writer's cramp), use a fine-tipped permanent marker to write your invitation on a domino mask. Mail in oversized envelopes or small boxes.

• For a small group, you can also get creative with delivery. Send "hand-delivered invitations," wrapped around a plastic skeleton hand.

• Your invitations dealer may be able to provide elegant autumn-themed cards featuring fall leaves or pumpkins. Ask if they have any "Halloween party" invitations which might be able to double as wedding invitations.

• Tiny Tidings offers a selection of invitations for Autumn, Fall, Halloween and Gothic weddings.

• Of course, you can always simply "spook up" traditional invitations with clip art images of ghosts or harvest scenes. Select sombre colors in greys and blacks, or dramatic tones of blood-red and pumpkin orange.

• 4 Halloween Coffins offers a variety of cardboard coffins, including some suitable for use as envelopes. Decorate them with stickers, markers, or paint for a personal touch.

• Check out the Ceremony: Poetry and Invitation Wording pages for ideas on invitation wording.

• If you want your guests to arrive in costume, be sure to say so on the invitation. If you want them to expect anything "non-traditional," it's a good idea to include a newsletter-type insert or create a Website to tell them exactly what you'd like them to do, wear, and bring.
