About putting on duvet covers. Get four clothes pegs. With the duvet cover open and pushed up so you can easily access the two top inner corners of the cover, take one corner of the duvet, place it inside the inner corner of the top right hand side and, on the outside, peg it in place, then do the same on the left hand side. Shake down the duvet cover. Peg both bottom corners of the duvet to the inner corners of the bottom of the duvet. So, now all corners of the duvet are pegged. Shake the covered duvet and remove the pegs.
I know it sounds like a flaff but, actually, it's easy and works well
