Wool is a great insulator, so it works well against winter chills. Cut a long tube from a sweater arm or body, stuff it with fabric scraps, cotton or old stockings, and stitch both ends closed. Place it at the bottom of a door or window to block cold air. For a pet, stitch two large pieces together on three sides, fill with scraps, and close the last side to make a cosy cushion bed. Cats and small dogs usually take to the soft, warm fabric straight away.
