Was wondering why the double bed duvet I use on the single bed (extra coverage over the sides of the bed) was always getting out of shape/place in its cover. Reason: I’d been using a queen size cover and a smaller double quilt. Never had a chance.
Rectified now. I measured each spare cover, there’s one single, two double and a queen in the spares dept. In use on my double bed is a queen size lightweight duvet and cover. In the cupboard is a heavyweight winter queen size duvet and cover.
