Insulated drapes seemed the way to go, but the commercial solutions were frightfully expensive and seemed rather flimsy to me.
The other day I purchased an "inexpensive" quilt in a neutral grey, as well as some curtain rings with clips on them to allow one to clip their own fabric up.
I put in a few hooks above our bedroom door and we tried it out.
