Claudia Winkleman hosts The Great British Sewing Bee as the eight amateur sewers prepare to do battle again in three challenges designed to test their ability to handle stretchy fabric.
The judges - Savile Row's Patrick Grant and sewing expert May Martin - first give them a surprise pattern for a simple pair of leggings with resulting snug and saggy bottoms.
Next, the sewers are free to do whatever they like to turn an oversized T-shirt into a completely different garment - and they come up with some ingenious alterations, from a toddler's leotard to an asymmetric minidress.
Finally, they face the most fitted made-to-measure challenge yet.
