Another item that helps keep shoulders warm is the shawl that has pockets on the ends. I don't remember the pattern right now. It is a long rectangle with turned up ends to make the pockets. There is also one that can be knitted or crocheted.
Mother had several triangular and half circle knitted and crocheted shawls we took to church to keep the air conditioner's cold off our necks during service. They were shorter, more like capelets that came across our backs close to our shoulder blades, then closed in the front. ( My girls would always tease about looking like "old" ladies. But were warm and cozy- kept them from wiggling so much. )
