The Great British Sewing Bee - Series 4

Ten home sewers must follow a deceptively difficult pattern for a woman's top made up of four pieces.

Nine sewers return hoping to show the judges that they can make beautiful clothes on a miniature scale.

The sewers take on delicate lingerie, working with fiddly pattern pieces and the most delicate fabric.

Patrick and Esme set the seven remaining sewers the challenge of tackling techniques and garment styles from other cultures and continents.

The sewing room is transported back to the 1960s as the six remaining sewers try to prove they deserve a place in the quarter-finals.

In the quarter-final, the five remaining sewers sweat it out over activewear, creating complex garments from the most technical of fabrics.

The sewers must make an asymmetric yoked skirt inspired by modern Japanese pattern cutting.

The three finalists create three pieces of evening wear to impress the judges.
