Here is a resource I wish I had known about earlier!
Google Docs Wedding Planning Tools in association with Style Me Pretty is a set of fantastic wedding planning templates, making it easy for you to save information, share information and best of all – access these docs from anywhere with WiFi. Although there are templates for several different things, my favorite has to be the Address Book.
The Address Book allows your guests to fill out their information directly from their email, which is then stored in a spreadsheet, saving you the hassle of cutting and pasting into your own home made spreadsheet. This is super handy because, as I found out when I was addressing my invites, we rarely know our friends addresses these days since snail mail went out of fashion, and people move around so much.
I will certainly be using the Seating Chart (which is next on my to do list) and the Day-of Schedule, which gives an excellent time frame for your own day.
Having it online makes it very easy to share with fiancee, family and bridal party, especially if they have gmail. If they don’t, you can still send them the link in order to enable to view the latest goings-on.
