Nobody shares a throw. These are sized for one person and one sofa — shoulder to knee, light enough that pulling it over isn't a decision you have to make.
Leave one folded on the arm and it stops being a blanket and becomes part of the room. All one size, all natural fiber — wool, lambswool and cashmere, or baby camel hair.
Murmurs makes open-front wool and cashmere capes, wraps, vests, and blankets, designed to be worn while working from home and out of the house — comfortable enough to rest in, presentable enough to be seen in. One size, no closures. Founded by a former tech designer.
