Hamilton's artistic career began when she started selling her creations in her mid-teens. A true multi-crafter, she is proficient at embroidery, macramé and crochet but finally settled on handknitting at the age of 22. After a design and hand knit career in New York, she moved to Sweden, eventually opening a yarn store. To date Cornelia has written 15 pattern books for knitting and written numerous articles on the history of knitting in Sweden. She now divides her time between Sweden and America, giving workshops and lectures at trade shows and retreats and marketing her yarn line, Heaven's Hand.
