I believe it is called a bed scarf and I have seen them at Targets. Hope that helps :>)

I think that the new bed linen style some hotels use might be safer. Typically hotels don't change blankets and spreads between guests...ewwwwww! But I have noticed in some of my recent stays the beds are made with a top sheet, blanket, another top sheet and the bed scarf. At least your body is not against the blanket or a spread. Thanks for posting this topic, I never knew the name either. :-)
