Joe Lycett welcomes the ten remaining home sewers back to the nation's most famous sewing room for children's week. The garments might be mini, but they are a mammoth challenge because they are fiddly to sew.To test the sewers' dexterity, judges Patrick Grant and Esme Young kick off the pattern challenge with a classic for any little girl's wardrobe – a smocked dress. The task requires the sewers to combine tricky techniques, including making a bias binding and a Peter Pan collar, and, most difficult of all, creating a smocked bodice. Next, in the transformation challenge, the sewers let their imaginations run wild, turning sleeping bags into food shaped fancy dress. Finally, the Sewing Bee welcomes mini-models for the made-to-measure task, which is to make a pair of dungarees for a girl or boy. These must be perfectly fitted but allow enough freedom of movement to play in.Who will climb their way to the top and win garment of the week, and who will stumble, becoming the third sewer to leave the Great British Sewing Bee?
