I've been asked this question a lot lately, so I thought I'd post some helpful hints from my friend Allison Howell with Ink Invitations. "We often say that the invitation is the first experience your guests will have of your event. But that's not always true. A memorable save-the-date card can build even more anticipation for your celebration."
The facts:
Save-the-dates (aka "STD's") should be sent six months to one year before the wedding.
Include: accommodation and travel info w/ the STD so this can allow the guest to plan early. Flights, rooms, and activities may not be available if they don't receive that information until they get the invitation.
Necessary or not? STD's are not always necessary but they do allow you to express yourself, inform your guests, and build excitement for your celebration. They are necessary if your event is over a holiday weekend or a destination wedding. Even any events held between November 20th and January 3rd.
Thanks Allison! For any more info, please contact her at allison@inkinvitations.com
