Under house arrest, Mary Queen of Scots used needlework to communicate with the outside world. Scandinavian artist Hannah Ryggen made radical political statements against fascism through her spellbinding tapestries.

Marit Paasche (Hannah Ryggen: Threads of Defiance) and Clare Hunter (Threads of Life) weave a fascinating story of identity, protest, power and politics with Rosie Goldsmith.
