Kassia St Clair, bestselling author of The Secret Life of Colour, and Polly Mason, Liberty’s Head of Design, join Sevenoaks Literary Festival to discuss 'Liberty: Design. Pattern. Colour.', which has been published to mark Liberty’s 150th anniversary.  150 of the most striking and significant Liberty patterns, ranging from much-loved florals to bold and abstract designs and contemporary collaborations have been brought together to tell the brand’s story. The book places fabrics in the context of the store’s wider design history.
