The early mills used the putting out system in which the mill did carding and spinning, but hand weavers were paid to weave the fabric then return it to the mill for finishing. Then, in the 1830s, improved machinery allowed mills to do the entire process with machines, greatly reducing the cost of cotton cloth. In 1841, power looms that could manage wool were developed and affordable woolens appeared.
