And this what I found at candle/glassware aisle:
First, take out the sticker tags attach on it.
Plug the glue gun to heat up
Fill-in hot glue around the side of the candle holder.
Attach the candle stick holder at the button of the vase.
Make it sure you centered it.
You can put candles, pebbles or pine cones. Maybe I should etched our lastname initial next time when I have more time :)
