The six home sewers are taken out of their comfort zone by Claudia Winkleman when the judges set them three challenges which require them to handle some of the most difficult fabrics to sew with.The surprise pattern is for a nylon anorak, which means ironing the garment could prove disastrous.For the first time, the sewers handle something which isn't a textile, as a high street top is transformed with leather. And, in a new twist to the series, they pair up to be each other's 'fit buddies' as they are asked to make a pair of trousers for themselves - in delicate velvet.
