The Great British Sewing Bee does its bit for the planet with Reduce, Reuse and Recycle week. Host Sara Pascoe invites the nine remaining home sewers to create a quilted patchwork jacket from a load of old scraps from past Sewing Bees.

Next, in the Transformation Challenge, the sewers breathe new life into boring old coats by completely deconstructing them and refashioning them into brand new stylish outerwear.

For the Made to Measure, the sewers fit a maxi dress to a model using only an unwanted duvet cover. Who will ace this creative brief and win Garment of the Week, and who will have to leave the sewing room?

Music Week brings three different musical and sartorial genres to the Sewing Bee. Sara Pascoe kicks off the week with a pattern for the parka coat that was adopted by Mod culture in the 1960s. With its classic fishtail vent and complex zip opening and hood, this is a feat of engineering.

Country music is the inspiration for the Transformation Challenge, as the sewers take old denim and turn it into stage gear worthy of Dolly Parton. Finally, the Made to Measure is an homage to David Bowie and his many incarnations. The sewers pay tribute with Bowie-inspired outfits fitted to a model.
