Blanket Cover
A blanket cover is a very lightweight decorative covering that is layered over a blanket, almost like a decorative top sheet. A blanket cover is often used on hotel beds as the outermost layer over a blanket, protecting the blanket so it won’t need frequent laundering. The fitted sheet, flat sheet, and blanket cover can be pulled off the bed and washed in a single load. Blanket covers are usually poly/cotton blends, requiring very little attentions; no ironing necessary.
As polyester is made from a petrochemical, it's not biodegradable like natural untreated fabrics. It can also shed plastic microfibres when washed which can end up in our rivers and seas.
