It's a celebration of the autumn harvests.
So table centerpieces with lots of textures and mostly earthtone colors, like rusts, cranberrys, oranges, browns, beiges, reds, and yelows.
We use wheat and cattails, pods, ornamental squashes and pumpkins, cornucopias, baskets and candles. Different kinds of grasses - millets, broom corn. I always like to throw in purples, think it makes everything pop.
Here are some pics I took for my site.
