Episode list

Comedian Sara Pascoe, Dr Ranj Singh, television presenter Denise Van Outen and Strictly judge Shirley Ballas are the 4 celebrity contestants on this special edition of the sewing contest.

Amateur sewers test their sewing and dressmaking skills. The contestants make an A-line dress, alter a high street top and create a made-to-measure dress under the clock.

It's Music and the Movies Week. The sewers create a dress inspired by Dirty Dancing, a Sound of Music transformation and a disco era-inspired outfit from Dreamgirls.

The fabrics in the haberdashery go technical, as the seven remaining home sewers take on man-made fabrics designed for sport and the great outdoors. Host Joe Lycett keeps spirits high, as the sewers jump in at the deep end, with a pattern for a lined swimsuit. Containing so many seemingly identical pieces, it's a challenge that throws the sewing room into confusion, with a great deal of conferring, before judges Patrick Grant and Esme Young offer their brutally honest feedback. Next, the transformation challenge arrives with a surprise, as instead of garments, the sewers are presented with discarded festival tents. What's more, a dashing dachshund becomes the sewers' muse, as they attempt to transform old tents into stylish, practical winter coats for pooches, to be displayed on dog mannequins. For the final challenge, male models arrive in the Sewing Room to be fitted with made-to-measure luxury tracksuits. It's double the work for the sewers, who attempt to create both trousers and jackets, using scuba, mesh and micro-fibre. But who'll deserve a podium finish, winning Garment of the Week, and who'll fall short of the mark, becoming the fourth sewer to leave the Great British Sewing Bee.

It is the final of the 2020 edition of the sewing competition. The final three sewers face challenges around the theme of celebration wear and the series winner is crowned.

The sewers face a no-waste challenge, have bags of fun in the alteration, and battle with crochet.
