Wow. I had no idea this thread was back in action... Back when I originally wanted to do it (hi, I'm the person who started this thread), only one person msgd (yardenxanthe) saying they would help out & then she said she couldn't (and now she moved away, I think).... so it just never really went anywhere.
But I'm back now & would love (x10000) to do this.
I set up a temporary website for craft fair plans to be posted on my domain at: http://www.prettyinprint.net/craftfair.html
Once a name has been selected, I will get the domain and set up the official site (for anyone, not just planning info).
So, anyone interested in helping plan/work this thing? I certainly cannot do it by myself, but I would love to see it happen.
Email me at sarah at prettyinprint dot net to let me know you're interested in helping... I will send out a group email to whoever volunteers and we can start discussing.
