Unless you're a professional floral designer, or have a lot of money to spend on decorations, it's likely that you don't give much thought to centerpieces for your Thanksgiving table. But with a little creativity and an eye toward color, it's not very difficult to create your own centerpieces using items that are easy to find around Thanksgiving, and cost much less than a professionally purchased arrangement. You can even create some that become edible once the holiday is over!
