Massachusetts is home to many manufactured goods. Its cloth-making industry began in 1814 in Waltham. Then, shoemaking became important in Massachusetts. To make paper, people in Massachusetts used textile mills to make sure that the paper was made smooth, not rough. They also used those mills to make rubber products.
