Heavy throw blanket

Why would anyone seek out a blanket that is particularly heavy? Perhaps it is because there is a certain comfort that comes from a heavier blanket. A sort of feeling of security. It’s something you just can’t experience with a light weight blanket, no matter how warm it may be.
