    Paula Gamester MBE, social enterprise The Sewing Rooms

    Paula Gamester MBE, founder of the social enterprise Connector Media CIC and co-founder and of The Sewing Rooms, which upcycles, recycles and diverts textile waste from landfill, tells Kevin the story behind the creation of The Sewing Rooms, how she brought the thermal cooking bag to the UK to help tackle cost-of-living challenges and reduce carbon emissions, and gives her tips for running a sustainable social enterprise. For full transparency, this episode was recorded late in 2025 and The Sewing Rooms has since gone into voluntary liquidation. We recognise that many third-sector organisations like this are operating in difficult times, particularly in relation to available funding sources and rising costs. This episode is published because it has such an inspiring message and themes which remain as good learnings on sustainability for listeners in the fashion, third-sector and other industries.
