first art show

I got my ABC canopy on Amazon. Love it because it goes higher then the basic pop-up.

you can rent tents. check with the promoter, you may be able to rent a booth display(panels). many shows offer full pro panel booths to rent. is this outside? you can pick up a set of wire display panels pretty reasonable $$. a small table with a cover and some bins or print racks to display prints and cards.
if you invest in a tent you can use the wire displays for your wall art. also look into Flourish mesh panels. they are easy to put up and come in black or white. Flourish panels are the only thing i use for outdoor shows. my propanels i reserve for indoor show events. check Artist Network for used equipment, you might find a deal there too.

I use and ABC canopy with the white sidewalls (from Amazon), then I put up a top and bottom rail purchased from Flourish, and then I zip tie white display grid panels to the top and bottom rail. It eliminates the wonkiness of having the grid panels sit on uneven ground. The white on white minimizes the visual noise of the display grid. I ordered a printed tablecloth from Bannerbuzz.com totally reasonable price.
