Since the Stationery Show is in town I thought I'd write some posts on wedding stationery.
If you are including a set of directions to your ceremony and reception sites in your wedding invitation it's always a good idea to test drive them. Your venues will probably have pre-made cards that you can use and it's a safe bet that the direction on them are correct. But give them a once over just to check they didn't miss a typo.
You can also ask your stationer to create a direction card that matches your wedding invitation's design --for us, for lack of a better word, anal brides. Me including.
If you are having the cards printed, I suggest double and triple checking the directions you are giving because once you sign off on the proof you are responsible for them. If after they are printed you realize you wrote left and you meant right it's on you to re-print them and pay for them, as well as any rush fees that may apply.
In addition to you and your fiance proofing the directions, don't be afraid to ask the venue's location manager, a friend, member of the bridal party or a parent to proof them to. And you may even want to get in the car any actually try them out to confirm that they are correct.
As for where to get the directions, your venue may have them listed on their website or in a brochure or you can use MapQuest. Make sure to get the directions from multiple directions - north, east, south and west. And if you are getting married in an area with mass transit you can also add those directions too. HopStop has train, subway and bus directions for many metro areas.
