Fix wet towel in front of the window
Since it is getting warmer again, there is the possibility to hang a wet towel in front of the open window / balcony, to bring a little cooling in the room. Now I had the problem of fixing. Since a wet towel weighs a bit, I did not want to risk that the curtain rod might come in handy.
Then I remembered the rolling clothes rack, for which we currently have no use. So I grabbed this, set the pole as high as possible and hung the wet towel almost the entire length, fixed it with clothespins and placed it in front of the open balcony door.
It does not look pretty, but it does its job and is quickly stowed away.
