Scott~ Don't let it get you down... there are a milliion different factors that go into how successful you are at a show. The biggest like Griz stated is the type of show, get a publication like sunshine artist or the art fair source book and try some of the shows in there. My first show almost 3 years ago now... I made $53 (but the lady got almost $100 worth of stuff) I now do about 30 shows a year traveling almost 1000 miles for the really good ones and I average about $2500 per show... some better, some worse but that is an average show. Don't kid yourself I spent a lot of money and worked VERY hard to get to that point, but there is a very definate market out there you just have to find it. Feel free to e-mail me if I can be of any more assistance.
Good Luck and Happy Scrolling
