I love craft fairs. I've only done two, but I'm completely hooked. I love setting up my items, and then fiddling with them, and then rearranging them. I love talking to people about my creations, and meeting new people. I know that sounds like the worst thing ever for some sellers, and honestly I thought I'd hate it. I have a bit of stage fright, but at craft fairs I just have so much fun.
So far I've only done tiny shows, one of which I barely made $100 over two days. But I liked chatting with parents, and showing off my toys to kids.
One thing I recommend to others is to check out the fairs and shows ahead of time. I love the major fairs, but luckily I've checked them out before applying. I am DEFINITELY not ready for that! I have so much respect for those people who sell at the nationally known shows. If you're one of those sellers, my hat's off to you.
I've also been to shows that seem lovely, but just aren't for me. I went to a permanent show this weekend which was absolutely gorgeous, and the people who worked at it were so nice and friendly... but it was a 90 minute drive through nasty traffic. If I lived nearby, I might be tempted. Plus, the foot traffic in the show was pretty slow.
On the other hand, a few weeks ago my friends and I met up at a local brewery. Lo and behold, there happened to be a super tiny craft show! I had no idea! It seemed to be in the very beginning stages, but super cute, and in a brewery! My husband and I are beer geeks, so it works perfectly for me.
Another thing that's helped me out is the many craft fair checklists. Here are a few really good ones: https://www.etsy.com/seller-handbook/article/what-to-bring-to-a-craft-fair/22715491953
