Worsted “stuff” was a term that referred to a wide variety of worsted textiles produced originally in Norwich and later in York. These lightweight goods were characterized by their tightly twisted yarn, fineness of weave and smooth finish. This made the wool well suited to Men’s and Ladies' garments. The grades of stuff varied from coarse to fine and could be plain or twill woven. The name cadet blue is a fairly modern one coined in the 20th century to describe the distinct blue color used in uniforms. This color in the 18th century would have simply been known as blue. In our studies we have looked at a variety of wool dye receipt books. Often we found no distinguishing names for the variety of blues achieved. Their were a few distinct names in the 18th century such as saxon blue, robins egg blue & sky blue which evoked a specific blue color however we have not found to date a distinguishing name for this color.
