Here is a PDF with some craft show tips that I hope you will find useful.
45 years ago when I started selling my Christmas ornaments I really could have used some craft show tips. We did not have the internet back then so doing research on shows was a bit hit and miss. I was very fortunate to be juried into the shows of 2 of the best show promoters in the country and I sold my ornaments at their shows for over 30 years.
So, take a look at the PDF for some craft show tips. I hope it helps you in some way.
May all your shows be profitable!
