Depending on your location, fall weather can certainly be unpredictable.
One sweet gesture in anticipation of chilly temps~ is to have wedding throw {blankets} handy for guests to quickly grab and wrap around themselves. Certainly perfect for outdoor ceremonies but also for guests who wander out of doors at the reception. Guests love to wander you know. And, even more so if there is seating outside too.

Lay them over ceremony chairs or roll and tie them up and place in a cute bin like this bushel basket... thoughtful and adorable!
