Turn the duvet cover inside out by reaching inside, grabbing the corners and pulling them inside out. Flatten your duvet onto the bed so it is easy to locate and grasp by the corners.
Place your hands inside the cover at the two furthest corners.
Pull the corners into the cover. As you pull the corners inside, pull the duvet cover on top of the comforter so the duvet is inside. Shake the blanket to help with this process.
Pull the two bottom corners inside the duvet and hold the duvet by its top two corners. Shake out the duvet so it is evenly dispersed inside the cover.
Zip up the bottom of the cover or do up the buttons. The duvet is now ready to be used as a blanket for your bed, or you can curl up with it on the couch.
