To create a centerpiece that’s pretty and affordable, use a terrarium, vase or lantern you already own. Fill with any type of vase filler that complements your color scheme. I found an inexpensive bag of mini faux pumpkins to fill my terrarium. To bring more prominence to your centerpiece, place the vessel on a slice of wood from your backyard. Just be sure to sand it well and seal it with a thin layer of butcher-block oil beforehand. Pro tip: While you’re at it, make a few wood slices, as they’ll come in handy for the food buffet, drink bar and leftover station, as well.
