A duvet cover is comprised of a base sheet and a top sheet interconnected toghether by a peripheral stitiched seam. A down feather sheet is retained between the base sheet and the top sheet. The down feather sheet has a substantially constant density of down feathers with the down feathers being retained captive by a binder whereby the duvet cover has a susbstantially constant insulating factor throughout because the down feathers are immovably retained therein. Such a duvet cover permits the creation of all sorts of stitched or quilted designs therein without concern for the propagation of the down feathers between the base sheet and the top sheet of the duvet which would create irregular insulation. |
