Claudia Winkleman presents a contest in which eight people compete to be crowned Britain's best amateur sewer. They are given three challenges, beginning by following a simple pattern for an A-line skirt, before transforming a high-street top by altering the neckline and finally producing a made-to-measure dress for a model under intense time pressure. Judges May Martin from the Women's Institute and Savile Row designer Patrick Grant pick one garment as the best of the week and select which two contenders must leave the Sewing Bee.
