Measure the plank and divide the length by the numbers of jars you will place down the area. Line up jars in a single or double row, depending on your preference.
Turn the jars upside down on the plank evenly, based on the measurements from Step 1.
Draw around the jar rims with a pencil to know where to cut the holes.
Attach the hole saw to the drill and cut out the circles.
Smooth the hole edges with medium-grit sandpaper for a finished look or leave a rough edge for a more rustic look.
Drill smaller holes at each corner of the plank, making them only large enough to thread a piece of sturdy rope through each one.
Place the plank on a work surface so the side that will show -- once you hang the chandelier -- faces up.
Add a large stream of glue just beneath the rim of a jar. Use a hot glue gun or an adhesive that bonds glass to wood.
Set the jar upside down into the hole before the glue dries. Wait for the adhesive to try before continuing. If you are using hot glue, this only takes about 10 to 15 seconds. Read the instructions on any other adhesive for that drying time.
Flip the plank over so the jars support the weight of the wood.
Cut four equal lengths of rope with a sharp knife. The lengths depend on how high the ceiling is and how low you hang the chandelier. Seven feet from the floor allows people to walk underneath a chandelier in a foyer or living room. An appropriate distance above a dining room table is 30 to 32 inches from the table surface.
Thread a piece of rope through each hole and tie a simple knot in the rope directly beneath each hole. Continue with all the pieces of rope to add a country-style charm to the chandelier.
Place a tea, pillar or battery-operated small candle in each jar.
Tie another knot in the ends of the ropes that will be closest to the ceiling. Put screw hooks in the ceiling and place the knots in the hooks to hang the chandelier.
