Take the time to thank your wedding day vendors if they did a great job (which they should have!!). A simple thank-you note (along with the hundreds more that you have to do) is not something that most brides do, but is very special. There are also several sites (like weddingwire.com) that you can use to rate your vendors. Those sites can help other brides decide who is right for their wedding.
You can even take this picture and print out note cards to use as your thank you cards! How cute would that be!!
