Patchwork blankets have always been considered averters in Ancient Rus. They were most often made of old worn clothes of natural fabrics. They kept the smell of their owner for a long time. Therefore, mothers sewed blankets for their babies out of their clothes. The kid felt the "dear" smell and calmed down.
There was a belief that old clothes, in addition to the smell, also store human energy. Therefore blankets were considered averters as well as being the protection from the evil eye.
Patchwork blankets were also sewed before the wedding. The bride made it from the clothes of her relatives and relatives of the groom. The sewn blanket was a family heirloom. It was neither given nor presented to anyone. It was never taken out of the house and guests were not allowed to cover themselves with it.
