I've always entertained a variety of ideas when it comes to my actual [eventual] wedding invitations. Of course, half the battle is design & creativity. While the other half is finding the folks to properly put out the idea.
I'm especially fond of save the date reminders that run the gammit from magnets & calendars to more individualized cds of info... Wedding Needs seems to have it all very well (& diversly) covered! From announcements & invites to favors & wedding party gifts, they are a one-stop shop for a large part of the preparation list!
