A blanket scarf is a large, square or rectangular piece of fabric that can be worn as an accessory to keep warm. It's typically made from soft and cozy materials such as wool, cashmere or fleece, and can be wrapped around the neck and shoulders like a shawl or scarf. The name "blanket" comes from its generous size and thickness, which makes it feel like wearing a small blanket on your body. Blanket scarves are popular for their versatility - they can be worn in multiple ways to create different looks, such as draped over the shoulders or tied at the waist. They're also great for traveling because of their lightweight and compact size when folded up.
