I'm a Bad Blogger and a Craft Fair Question

I'm such a bad blogger.  I have been so stinking busy that I haven't been able to get anything posted.  I am going to be in my first Craft Fair in November and I have been working hard on getting stuff ready for that.

So, have any of you ever sold cards or anything else at a craft fair?  If so, how was your experience?  I have heard many good stories and some horror stories. 

I was able to get one challenge card made this weekend.  I just posted this on the Greeting Farm Facebook page.
