With Joe Lycett hosting, the quarter-finalists face British and Irish fabrics week. First up it is the pattern challenge, which this week is a stern test of their soft tailoring skills, as judges Patrick Grant and Esme Young ask the sewers to create a ‘worker's jacket' from linen. It is a garment full of complex techniques, using a fabric that can easily crease and fray, made all the more nerve-wracking as they must precisely follow Patrick's personal pattern.

Next it is the transformation challenge, and the sewers are asked to take inspiration from the British seaside by turning stripy deckchairs and parasols, covered in hard wearing Burnley ‘ticking' fabric, into stylish garments, in just 90 minutes.

For the final challenge, the models arrive in the Sewing Room to be fitted with made-to-measure coats, constructed from wool the sewers have sourced from across the British Isles. These are the largest garments they've attempted so far on the Sewing Bee, and the sewers must once again draw on tailoring prowess, to ensure their coats hang and fit perfectly. Whose wool coats will be the pride of Britain and who will unravel, missing out on a coveted place in the semi-final?
