Carpet manufacturers have played a role in creating and boosting the economy and profile of Guelph. They have been small, medium and large enterprises. Some, such as the Guelph Carpet and Worsted Spinning Mill were extensive in facilities and employed many Guelphites. Others, such as Clark and Thompson, were small companies that existed only a brief time as carpet makers before changing fields. Clark and Thompson became a dry goods retail store.
No matter what the size, the early carpet manufacturers worked most frequently, if not exclusively, with wool. The size of their work force and their market was also variable. The same applies to what was to change this industry, like so many others - mechanisation and the deskilling of the crafts.
