The Great British Sewing Bee - Season 2 Episode 7 -

The four semi-finalists face three challenges in which they are not allowed to use a pattern for guidance, having to fit a dress to a mannequin, add a pair of symmetrical sleeves to a garment and make a copy of a favourite item of clothing. Judges May Martin and Patrick Grant then decide which three will go through to next week's final. Claudia Winkleman presents.
