Margaret was introduced to clay at Bolton College of Art before continuing her studies at Stoke-on-Trent School of Art, where she was taught by former Bernard Leach apprentice Derek Emms. It was there that she met her future husband, David Frith. In the mid-1960s they established their first workshop, and from 1976 they were based in their 18th-century woollen mill in Denbigh, North Wales. From this setting they taught and made their work together for over fifty years.
