My 1st bad business experience and 1st street fair

Let me start by saying that things have been really busy as of late.  I was supposed to be teaching at the Art League of Long Island, but they let me know the DAY BEFORE I'm supposed to start teaching that the class is cancelled.  I can understand that with the economy the way it is, but not giving me a heads up until the 11th hour really pissed me off.  So in order to scrape some money together this sumer I've decided to try and peddle my wares at a few craft fairs.  I just had my first craft fair on Sunday.  It was the Hicksville Street Fair.  The week leading up to it was one of the busiest of my life.  On top of the nonstop errand running to get all of my booth materials together, I'm also in summer classes from 10am-2:30pm mon-thurs.  Luckily I got everything together just in time.  The event itself was a mostly a learning experience.  I encountered an unforeseen factor in the constant gusts of wind.  I also realized that the signs advertising my prices were WAYYY too small.  The crowd was also pretty low-brow and seemed more interested in Egyptian bed sheets ("One for 20!  Three for $50!" is all I heard for the better part of the day lol) than art.  The next show that I'll be attending is in a much more affluent area so hopefully I'll have better luck.
