Why in the countryside poor peasants and artisans began working for merchants?

In the countryside poor peasants and artisans began working for merchants that was a time when open fields were disappearing and commons were being enclosed. Cottagers and poor peasants who had earlier depended on common lands for their survival, gathering their firewood, berries, vegetables, hay and straw, had to now look for alternative sources of income. Many had tiny plots of land which could not provide work for all members of the household. So when merchants came around and offered advances to produce goods for them, peasant households eagerly agreed. By working for the merchants, they could remain in the countryside and continue to cultivate their small plots. Income from proto-industrial production supplemented their shrinking income from cultivation. It also allowed them a fuller use of their family labour resources.
