Oh the things you can do with a 2x4.
One of my favorites is making rustic candle holders. They are inexpensive and easy.
First cut the 2x4 to length I usually do 2ft. Then measure the placement of were you want the tea light candle to sit, remember they always look better in an odd number.
Drill the holes with a drill press or a drill to the diameter of the tea light candle. Paint and antique however you want it.
Then place in your candles.
I have made these for wedding gifts and family events. They are super cheap.
