Skip the expensive engraving and calligraphy and give your wedding a casual, modern twist with a video invitation. Use a simple Webcam or camcorder to record a short greeting for guests, along with basic wedding info. Make your video as funny or formal as you want to help set the tone for your wedding. This option is not only free, but also great for green weddings as there's no paper waste associated with video. Best of all, it allows you to share your wedding excitement with your guests, which will help get them pumped up for the big day.
E-mail your video to everyone on your guest list, and request RSVPs via e-mail.
