The more they remain the same. Isn’t it amazing how we can look back over our lives and review memories from years ago, yet cannot remember why we went to the fridge a moment ago?
Festivals, and the money you can make at them, will create those memories as well as the type of income you can only dream about. Find the right type of craft (one that you enjoy, are good at and others like to buy) and your only limit is the amount of effort you wish to invest in the process.
For instance: If you like to paint, but you only want to dedicate an hour per week, then you probably won’t make a lot of money on your paintings. Unless you paint very quickly! But if you have the time to work on your paintings for several hours per week, you can build up a decent amount of art to display and sell at the festival. Hence .. more money.
