Bulk manufacturing arrives.

By 1910, the first power looms were installed requiring further expansion of the mill building. A new diesel engine was installed to run the machinery. The mill became famous for its quality, colour and design. William, along with his brother George, acquired another mill in Carlisle and Otterburn Mill became a brand leader in woven cloths.

Rena Waddell

By the late 30's Rena, daughter of William, took charge of design and marketing for the Otterburn ranges and became a fashion icon. Such was the popularity of the materials and designs, that the Mill's products were sought after by members of the Royal family. During this period, Otterburn produced tweeds which were adopted by such notable fashion houses as Dior and Schiaparelli, Balmain, Pacquin and Jaques Griffe. Garments were often featured on the cover of top magazines such as Vogue.
