This vase, made of paper, is very simple to make!

You can take thick paper or cardboard.
In the video, I take a rectangle of 27 cm by 12 cm.
The vase is 12 cm high, which you can change as you like.

It can be used as a cup for stationery :)
If you want to keep fresh flowers in it, place them inside a jar of water.

All the details are in the video:
