I use a little paper bag I got with a souvenir. But you can also use bigger things!

Take your bag

Fold it in half

And fold into the middle from the side

Make a square

And put your hand in then it's easier to do the next step

Make to triangles in the bottom

Cut with a scissor the height of your candle holder

About 1 inch higher cut around

Fold the edge down

My fancy tape! Choose one it's hard😏

Start from top edge

Tape over the triangles

Done!😋

I hope you will try it! The look very nice in the evening turned on🔦
