I have been a vendor at Arts and craft shows for about 7 or 8 years. When all is said and done, I don't think you make very much. The juried shows keep creeping up in price and the profit keeps going down. I still do a few local shows during the holidays. I don't live in a good area for this. You need to be n a big city. The rule of thumb use to be that you should bring in 8 to 10 times the amount you paid for getting your spot. It is a hard way to make some money. I noticed thing are high priced on Esty also. I put some baby blankets on Esty a few years ago and never sold one.
