I’m planning to do the same. Make flyers for it, post them online and irl, make it a party, do it at an air bnb, apartment, abandoned warehouse, wherever. Then you can make the vibe whatever you want, pick the music, make food, whatever you think fits your art. Can do some networking there, who knows who’ll show up ! If you document it, I’m sure more established institutions will be impressed at you putting on your own show if you decide to apply for your next collection of work. At the very least, you can throw a fun party with your art on the walls !
