The green thing has been sort of a huge deal in the wedding scene as of late, which means more and more couples are going for a paperless (and thus paper invitationless) event. But just because you're opting for an e-vite instead doesn't mean you have to miss out on any of the fun design elements and stunning presentation that a standard invite would bestow upon the recipient. Saving a few trees isn't the extent to which you can totally modernize your RSVP's.
If you consider yourself to be part of a rather hip couple, every wedding detail should bear your stamp of impeccable style. Graphic design nerds should especially take note - this is your chance to create an original work of art by digitally remastering a photo of yourselves or by creating a unique logo or piece of visual art to alert your guests of the impending ceremony. And even if neither of you know how to get down with Photoshop, there's a good chance you have a friend who'd be more than willing to take on the assignment.
What's more, new media gives you a whole range of options when it comes to presenting your final masterpiece. You can go ahead and set up a website or use email, but creating a flash animation or a fun, creative "wedding trailer" will be that much more enticing to your guests.
If you go all out for your invitations, you wouldn't want your wedding favors to pale in comparison. Creating unique do-it-yourself wedding favors is another great way to showcase your talents.
