The trick to affordable Thanksgiving decorations is to use your natural surroundings. Do you have pine trees and maple trees in your backyard? Then use them in your decorations! If you can find cheap pumpkins, gourds, apples or cranberries, then buy them to use for your Thanksgiving decor and work with what you have in your home already (vases, candleholders, jars, etc.).
Cover artificial pomegranates with copper leaf for festive decor that will never spoil. Just insert wooden skewers into artificial pomegranates. Coat each with adhesive size. Stand skewers upright in a piece of Styrofoam; let pomegranates dry until tacky (about 7 minutes). Following manufacturer's instructions, apply sheets of copper leaf until pomegranate is covered (approximately 2 sheets). Repeat with each pomegranate. Display on a tray, in a bowl, or on a cake stand.
