NIFTY NEEDLEWORK

The Great British Sewing Bee, 9pm, BBC1

PRESENTER Sara Pascoe (pictured) introduces a pattern challenge first in the sewing room tonight as the contestants are tasked with creating a rucksack — and there’s a big trap waiting when it comes to attaching the straps. The transformation challenge stays on the stranger side of things — turning a beach windbreaker into a waterproof garment — while the made-to-measure sees the sewers caught up in a stretch fabric nightmare as they try to make swimsuits.
