What would you do with if you could earn some extra money?

OK. Everything costs money. Think of what you could buy if you had a few hundred dollars extra cash?

As a student, I cut up beaded necklaces which I bought really cheap. The necklaces were hideous but there were a lot of really nice beads in them. They were just badly combined.

I bought the earring hooks and wires and converted each necklace into dozens of trendy earrings and sold them for a really cool profit.

Back then, I sold them through friends to their friends. Now, there are net auctions.

Lots of people are making money selling through ebay and other auction sites.

Competition is keen these days. Information is what gets you ahead. Of course your product must be good too.

You can do it from scratch. You can simply try again and again until you get it right. Or you can learn from other people's experience.

In real life, your meet the customers in person to convince them to buy your goods. On the net, the words you write on the auction site would often determine the sales you make.

There is a book that teaches you how to write to sell. It is called Make Your Words Sell. It is written just for the internet.
Be smart. Learn from the experiences and mistakes of the pros.
