This week, the sewing room is transported back to the 1960s as the six remaining sewers revive vintage garments, take on time-honoured techniques and wrestle with antique equipment in an attempt to show Patrick and Esme they deserve a place in the quarter-finals.For their first challenge, the sewers are asked to follow a pattern for an iconic 60s colour block dress. With multiple panels and clean, crisp lines required, precision is everything. For their alteration challenge, the sewers take a classic 1960s rainmac, but trying to make a wearable garment from PVC is no mean feat. For the made to measure challenge, the sewing room goes from squeak to chic as the sewers try to create impeccably fitted, flawlessly finished 1960s-inspired jackets. There are only five places in the quarter-final and with such a labour-intensive, tailored item as a jacket to perfect, the stakes have never been higher and achieving the perfect sew has never been harder.
