FYI, for everyone reading this thread and wanting to know more, for craft fair advice, I've found the team "Craft Fairs...It's a Living!" to be ABSOLUTELY the most valuable source of advice I've had.
Etsy Success is also awesome, but that's just a concentrated version of the craft fair awesomeness you can find here.
Also, who knows why some craft fairs don't work? I don't. I did my first one last month, don't have any new ones in view (the other options are all too pricey for booth fees), but I experienced exactly what I thought I would: most people didn't "get" my stuff.
But a few did, and those people went from item to item laughing and chatting with me and bought multiple things. We were clearly kindred spirits. That's the advantage and relative disadvantage of having a niche item. And for me, that's why online is so awesome, because you don't have to rely on those people who "get" your stuff to be living nearby.
I hope you find your audience, Mary!
