It's Kids' Week in the sewing room, and Sara Pascoe invites the seven remaining sewers to follow the pattern for a child's dragon dressing gown. The task requires the sewers to use a thick towelling fabric to create the dragon spikes, while the rough seams need finishing with a neat binding. The hood is topped off with googly eyes and spiky teeth.

For the Transformation Challenge, the sewers personalise denim jackets using hand-me-downs. They can applique, add trims or totally deconstruct the jackets.

Finally, mini models are welcomed for the Made-to-Measure challenge, which this week is to make special-occasion outfit for a five-year-old. As well as being party-ready, these outfits must be comfortable, allowing enough movement for playing games and dancing. Who will win Garment of the Week, and who will have to leave the party early, becoming the sixth sewer to leave the competition?

The quarter-final sees the five remaining sewers make garments inspired by history's most influential fashion Icons.

For the Pattern Challenge, judges Patrick Grant and Esme Young draw on old-time Hollywood glamour with a dress reminiscent of Audrey Hepburn's little black dress in Breakfast at Tiffany's – a garment that demands a tight-fitting bodice and elegant cut.

The Transformation Challenge is inspired by the Sewing Bee's very own fashion icon, Esme Young, and her work with fashion label Swanky Modes, specifically their range of clothes made from shower curtains, shot by legendary fashion photographer Helmut Newton for Nova magazine.

Finally, in the Made-to-Measure Challenge, it's an all-male affair as the sewers have been asked to make smoking jackets. This tailoring test is combined with tricky-to-handle fabrics alongside the added pressure of creating a perfect fit for their model. Who will secure icon status and win Garment of the Week, and who will be a fashion fail?
