I am doing alot of warm tones...chocolate brown, taupe, ivory...and LOTS and LOTS of candles!!!
You see alot of fall brides using oranges, reds, yellows to really compliment the season. I am a big fan of cranberry, champagne, ivory. I will look around from some inspiration boards for you and post as I find them!
Pumpkins are pretty popular too - a good friend of mine had her monogram carved into it and it looked great. I dont have pics but I am sure you can get the idea...I will look around for something similiar!
Did you take engagement photos? You could always use some of them for your STDs.
