Inspired by the story of Scottish entrepreneur William Tillie and the success of Londonderry’s shirt factories, four fashion designers create outfits from pre-loved cotton shirts.

The Ulster tartan is an interpretation of the Dungiven costume, and the inspiration for this week’s tartan challenge.

It’s elimination week and our designers will be challenged to come up with their own modern twist on the classic Ulster coat.

Taking inspiration from Ulster’s iconic linen industry, the two finalists go head to head to see who will be crowned this year’s winner of A Stitch through Time.
