You need this:
- Glass tubes (eg from House Doctor, about 5 Euro)
- small candles (eg votive candles or tealights)
- Rice wreaths (from the florist or craft shop)
It's that easy:
1. Put glass tubes over the candles. If necessary, place candles on a pedestal.
2. Place wreaths over the glass tube.
Tip: Do not allow candles to burn unattended and avoid drafts. Keep the burning bowl clean. If the candle smokes, wick shorten something. Only burn the candle on an incombustible base or use a self-extinguishing candle.
