Along with technology comes change and the wedding industry is feeling these changes more than most. Traditionally when arranging a wedding ceremony or function people send out personalized letters with self addressed envelopes inside so their family or friends could reply. Still one has to admit it is VERY nice to get these personalized invitations in the mail. It does however involve quite a lot of time and expense to do this though. Imagine if you have 100 guests. Thats 100 personalized let.
