A Money Making Blog

I plan of creating a blog for selling the ornament & other art I create. I'm thinking that getting a conversion rate optimization would be a good idea to use for getting traffic to the site as well as purchases. I know I am not going to make a ton of money, but it would be nice to see some extra money in my pocket. I really do enjoy painting & creating. It's a hobby, so why not make money doing what you love?
