Oh, I think we’re taking about a duvet cover? I believe that’s distinct from a blanket, which is usually sealed fully or a single ply.

I have certainly never been duvet levels of fancy.

One doesn't need to be fancy for duvet covers - merely live in a country where the duvet is standard and the blanket is secondary.

United States: Duvets are fancy. Norway: Common, everyday stuff.
