That black backdrop is such a smart choice — it makes all the colors in your work really jump out. The variety of sizes and styles you've put together looks great for drawing in different types of buyers. Good luck with the show, Muffy!
The black backdrops work except I rented a tent from the organizers and it was a circus style top with solid vinyl panel walls and no ventilation and was in the shade most of the day so the work didn't show well. YI had some turquoise panel drapes that I went back and added to lighten it up. Yesterday I got the show people to allow me to take down one of the side walls and rehung the booth and ended up selling a very large painting and a smaller one so I made a little bit of money
