The competition reaches its conclusion as the three finalists enter the sewing room for the very last time.
Judges May Martin and Patrick Grant must decide who has done enough to be crowned Britain's best amateur sewer, and they have saved their most complicated and demanding challenges for last. Across the three garments, they will be looking for avant-garde cutting-edge designs and the trickiest pattern cutting ever seen on the Sewing Bee.
The formidable first challenge sees the sewers taking on a pattern as complex as origami - with no diagrams to help them. The brain-teasing instructions almost prove too much for one of the finalists.
The next challenge sees alterations so extraordinary they leave Patrick speechless, and finally they are asked to fit an avant-garde dress for a model they weren't expecting, before Claudia Winkleman announces the winner of this year's Great British Sewing Bee.
