Welcome to the site. :)
The items listed in your booth look so adorable especially the fairy figurines. Your product descriptions are quite all right, generally your booth is pretty much well put together.
What products? That's a tough one, its quite hard to say you should sell this and not these. It will be even harder if you keep changing the types of products you sell. I read in your profile that you like collecting the fairy things that you are currently selling so I'd suggest you stick with that for now. It is often times ideal to sell (or even do) the things that we love or have interests in.
There are a number of things you can try to help increase your sales, one would be to increase traffic going to your booth. Another would be to offer promos like free shipping or even flat rate shipping - often times this works for most sellers. Also make sure you put up great photos with matching descriptions that are thorough, clear and concise(this one doesn't seem to be a problem for you).
I found a few articles that have various tips which I personally think may help you get more visitors and actually convert them to buying customers, please have a read:Link hidden: Login to viewLink hidden: Login to viewLink hidden: Login to view
