buying, selling on ebay, etsy or yorbin?

[Vulgarpollution563]

Unless you do a detailed analysis over time, it is hard to say what is affecting sales. I do etsy, used to do ebay until the fees killed me there, and a few shows per year. My BIG show makes money but . . . my first year was just my first year filling in for someone else, my second year was right after Hurrican Sandy, my third year they moved me to a different location. So, how can I possibly analyze my sales and whether it is worth doing the show with that kind of history.

You have the same issue. You don't have good data about who is buying, how the economy is affecting their income, how the demographics are changing in different regions, even whether or not you are using good keywords to get views. I've decided that this type of thing is not going to ever make me rich, so I don't depend on it. I just welcome any sale that happens along.
