If you're holding your wedding reception during Fall, harness those bright seasonal colors by gathering fresh leaves to use on your tables as centerpieces. Either leave them attached to their twigs for a textured three-dimensional effect that can be placed in jars or vases, or scatter them along the table for a really vibrant, rustic effect. Using the season as inspiration is a very common idea when coming up with themes for weddings and decorations, so this is a great way to do it with color and fun.
