All of the sites in the list below contain a Pandora's box of wedding ideas. You'll find listing of local vendors, discussion boards with topics from fellow brides, photos of the latest trends in fashion, flowers, and decorations, as well as some really awesome DIY projects that will save you tons of mula.
The Wedding Channel
Martha Stewart Weddings
Real Simple Weddings
For example, I found this adorable idea for a fall wedding on Martha Stewart Weddings: Instead of your flower girl tossing petals, find a small basket, line it with fall-time fabric and fill it with dried leaves.
Most sites will allow you to set up an account where you can store information such as your guest list, seating arrangements, budget, and wedding checklist. Beware: These sites will eat the hours in the day for breakfast. You may need to set the kitchen timer so as not to become completely absorbed and consumed by the abyss of weddings. I would, however, make a folder in your Favorites list for strictly for wedding resources like these. Enjoy!
