Joe Lycett is back in charge, with twelve of Britain's most talented home sewers competing to win one of TV's toughest creative challenges. Judges Patrick Grant and Esme Young cast an expert eye over the garments, in the contest to find Britain's best amateur sewer.Week One sees Patrick and Esme settling the contestants in with a trio of challenges based on everyday wardrobe staples. They start with their first Pattern Challenge, creating the simple, clean lines of the versatile classic sleeveless blouse known as a shell top. For the Transformation Challenge, the sewers must turn old t-shirts into completely new garments for men, women or children, in just 90 minutes. And in the Made to Measure, mannequins are replaced with real-life models. Who will whip up a well-fitting buffet dress and win themselves Garment of the Week, and whose hopes of staying in the competition will flounder?
