As a young girl Margaret E. Knight carried with her a notebook labeled My Inventions. She made creations for her mother and brothers and when she was twelve she designed a metal guard to prevent shuttles from shooting off looms and hurting workers.
Later she invented a machine that would cut and glue together a square-bottomed paper bag. Many of the paper bags we use today are still processed using Mattie’s invention.
