The first Scots-Irish settlers had to be self-sufficient because they were often isolated from other people by distances of miles. Food had to be acquired through gardening, herding and hunting. Cloth for linens and clothing had to be made by hand. Producing something as simple as cloth required that sheep be bred and cared for, and the wool sheared and made into yarn. The blacksmith was important to a community because it was he who made items for the home, such as pots and pans, wrought iron, and tools.
