A contestant on BBC2s Great British Sewing Bee cut the ribbon to open a new store on Bridge Street, Belper, at the weekend.
Mark Sanders, a historical costume maker who featured on the prime-time television programme, opened the shop, called Buttons and Bows Sewing Boutique, on Saturday, June 1.
The new venture has been launched by Donna Stanton - who will be selling fabrics and haberdashery and also running textile classes.
Mr Sanders was born in Holbrook and has lived in Belper all his life. He attended Belper School and is an HGV mechanic for his own company, Alfreton Cars and Commercials. He became interested in sewing and textiles in 2010 when he and his wife started making costumes that they wear to Steampunk events.
He departed from the great Sewing Bee after coming unstuck with a below-par fly during the trousers challenge.
