Last spring, my wife and I (she makes soap) went to a craft fair a few towns over. Someone involved in the American Legion in another town took business cards and contacted some other vendors and us for a craft fair they're throwing. Its a smallish town, but lots fo home-town pride, so we thought it'd be a decent time. We were misled.
First, this is the first time they were putting something like this on. We did not know that. We were told there were lots of vendors. 12 registered, and four other than us showed up. There were four larger events going on today for crafts within a 20 mile radius of the town, but they didn't even check on anything like that.
All done, we had less than 30 people show up (total) in about seven hours, no one spent a dime on my stuff, my wife made enough to make her table fee back. A very total wash. Gave out some business cards and one semi-serious lead, but nothing else.
On the bright side, we adopted a sweet lady pitbull last night and barring some adjustment pains with the other dogs, it's going pretty well.
