If you've tried the most common methods but still go nuts whenever you've got to put your duvet cover back on your quilt, consider reader claudelepoisson's advice and turn to one of our favourite multi-purpose office supplies: the binder clip.
Another use for binder clips: quickly and painlessly install a duvet cover.
Put the duvet in the cover one corner at a time, securing each corner with a large binder clip. Spread the combined cover and duvet on the bed. Reach the centre underneath and lift; hold it on over of your head with your hands and let the sides fall around you. Shake the duvet so that the sides fall to the sides of the cover. Spread the duvet on the bed and give the final touches. Remove the binder clips.
