You can drill holes from the bottom 1.5cm (you can use an electric drill, which is very dangerous, so be careful, I use an awl), not too close, and the distance between holes should not be too large, then use 502 (wax tears or other super glue can be used instead) to fix the candle head in the box, and cover it (don't worry that the lighted candle will go out because there are holes around it). Generally, you can sleep peacefully, because the candle will not fall down, and even if it falls down, it will be isolated by a box. In addition, the candle head will not burn for a long time, so it doesn't matter, so you can use it with confidence. I tried, but if the room area is not very large, don't put too much smoke, it will be a little choking.

You can try other patterns without punching holes. I once spent more than three hours buying a rose. It looked beautiful. At night, candlelight comes out of the cave, which is beautiful.

You can also fix a wire behind the cover and put some on the wall, which is also very beautiful.

This is a good idea to turn waste into treasure!
