Apparently this trick is called the “burrito” method. You start by turning your duvet cover inside out. Then, you place the cover on top and roll it up like a burrito, or pancake if you like. Best part is you can do it directly on the bed, so the task is accomplished immediately.
Check the video to see how she magically puts on a duvet cover with minimal effort.
Please forward this trick if you know someone who might want to learn this:)
