Other forms: cottage industries
A cottage industry is a small business run out of a person's home. If you make hand-dipped beeswax candles and sell them online, that's a cottage industry.
Before the Industrial Revolution, cottage industries made goods that were sold by a manager who oversaw the work of many individual households. The name comes from the work being done at home, in a house or cottage. In many countries today, these tiny businesses still support entire families. The vast majority of the handmade goods, clothing, and traditional crafts you might see at a flea market are the products of a cottage industry.
