craftgrrl | Some pretties and a request for craft fair advice

To all you experienced craftgrrls out there who have done craft shows and fairs: can I ask your advice? I've never done it before, so like... I am so terrified! I love making stuff, and I just have so much stuff I've made; I don't wear it all and I've given a lot away and still have quite a bit, so I've been thinking maybe I should do some craft fairs and try at least making more material or supply funds, because this hobby can be rather expensive.

I don't know, for instance, how much stuff is enough to make a good presentation? Is it complicated to get all the tax papers and such? Should I worry that my stuff doesn't look all the same style? What sorts of things shouldn't I do/have at my table? Should I be concerned about things like... well, that a lot of my wire jewelry is made from craft wire and not precious metals, for instance?

Anyway, here's what I've been working on.

My first pair of earrings:

I have some pictures of my second pair of earrings, my third bracelet, and some keychains under the cut.

Those ones above were loosely inspired by the earrings that character Emelia Rothschild wore in the short-lived postmodern television show, Jack of All Trades. ( You can kind of see them here: http://www.icelebz.com/celebs/angela_dotchin/images/photo18.jpg ) The ones below are my second pair of earrings. At first I wasn't pleased with the design, but when I tried them on, they are like so nice to wear in the summer. I've since grown to love them, but I don't know if anyone else would, so I may keep them.

My third bracelet ever:

I like bangles, can you tell? XD

Keychains:

I don't know if anyone would be interested in this sort of thing. They were a lot of fun to make, though. I also made the little wooden medallions myself; they were cut from pear tree trimmings, dried for a couple years, then I woodburned the designs into them, used Sharpies and craft stain to color them, and then finished them with a couple of coats of tung oil.

The whole shabang so far.
