Here's a sneak peek at my wedding invitations. I made these using Excel (my favorite design platform, if you look at my other instructables). I've got some screen shots to show you how it looks in Excel, as well as the finished printed product.
RSVP postcard (doublesided and interactive)
Map (doublesided with addresses and distances to locations)
Accommodations card with website
All fonts were downloaded for free from dafont.com.
These were printed on my hp deskjet 5150 on staples 110lb gray cardstock. They were then cut with a paper trimmer. The last piece will be an actual theatre ticket with the wedding information printed on it for the theatre we're getting married in.
