Joe Lycett hosts the quarter final, as the five remaining sewers go global, taking on garments and techniques from around the world.
First, they must follow a pattern they have never encountered before, as judges Patrick Grant and Esme Young ask them to make a Filipino terno blouse. Delicate-looking but deceptively robust, this garment involves difficult-to-handle fabrics worked into distinctive, voluminous butterfly sleeves and intricate covered buttons.
Next, it's the transformation challenge, as the sewers take on Provencal table cloths from France. These colourful, strikingly patterned cloths must be transformed into a brand new outfit in just 90 minutes, making imaginative use of the distinctive, bold print.
And for the made-to-measure challenge, the sewers take on the dramatic Flamenco skirt from southern Spain. They must create a perfect figure-hugging fit combined with impactful ruffles achieved by inserting yards and yards of fabric into the skirt.
Who will win a place in the coveted semi-final?
