Originally, my fiancé and I were having our wedding mid-October with an Autumn Harvest theme.  My mother (before we made any final plans) went out and bought a bunch of Autumn-themed decor (high quality silk leaves, high quality papier mache pumpkins, etc.)  Then we decided to have a Summer wedding.
I have two bags full of Autumn decor FREE to any Atlanta-area brides that want it.  
PM me if you're interested.  They're still at our house in Powder Springs.
