Make your dinner table look truly festive by tying a red or gold velvet bow to the back of each chair. Complement the bows with a matching velvet table runner and a simple centerpiece such as a clear glass bowl filled with small glass ornaments of red, green and gold.
Buy some inexpensive stemware and use glass paint to dress them up by painting stripes of alternating colors on the stems or some other seasonal pattern such as a green holly leaf with red berries. The holly leaf pattern would look great painted on plain white napkin rings, too.
If you don't want to use the stemware at the dinner table, fill them up with layers of colored sand and use them as a colorful decoration.
