Joe Lycett hosts as Summer Week hits the sewing room, with three challenges themed around sewing clothes to look and feel cool in even the fiercest heat.
Patrick and Esme's Pattern Challenge is a pair of paperbag shorts. They might be a small garment, but creating the signature shape means perfecting pockets, tackling tricky turn-ups and wrestling an elastic waistband with a mind of its own.
The sewers hit the beach in the Transformation, sculpting second-hand men's swimming gear into a woman's outfit worthy of sunset cocktails, all in just 90 minutes.
Finally, button-down sun dresses are the focus of the Made to Measure. As well as style, fit and finish, the judges have their eagle eyes primed for perfectly aligned buttonholes and secure fastenings. Who will miss the mark and be the second sewer to leave the competition?
