First Craft Show

I found out Saturday that I am going to be doing my first craft show in 3 weeks and I'm going a bit crazy. I'm excited and nervous all at the same time. I have read several posts in the forum on Etsy so I know what I need to do, it's just a matter of getting it all done before Nov. 14. The good part is that it is a small craft fair, at one of the local elementary schools, but still, I want to make sure I am prepared!
