Invitation from Design Sponge
The couple who created the invite above shared their really cute story with fun fonts and tongue and cheek banter. Despite being really cute it also serves a couple of purposes. Now all the guests will have some insight in the couples love story which allows for a more intimate connection. There's also the practical purpose of getting the story widely distributed so the couple doesn't have to retell it several times in one night.
Also, these sorts of invites are refrigerator worthy and by this I mean once the dates have been entered into your guests digital calender (the one they live and breath by) your invite, which you've worked so hard on, won't typically land directly in the trash as oh so many beautiful wedding invitations do. These fun how we met story invitations are also cocktail party story worthy and your guests will delight in knowing such as creative couple.
