This trick is so convenient! When the cold weather arrives, we try by all means to reduce our heating costs, because they are higher and higher. By making this door blocker, you will prevent the cold from entering a room or the heat to get out! See how to make it:
You only need two cardboard rolls and a nylon stocking.
Cut to keep only one leg.
Insert the two rollers into the cut bottom.
Pass the rollers on each side of the door.
Close the door.
There you go ! In addition to keeping the heat and blocking the cold, this allows better isolation of sounds and odors, a tool to keep on hand!
