Recently I attended an indoor market called the Wild Rumpus Market in the coastal town Thirroul (40 minutes north from where I live, and an hour south of Sydney).
The idea of the suitcase market is to simply bring your wares and some display props BUT NO TABLES. The stall space was 1.6cm square, so not a lot of room, but certainly not a problem.
There was a vintage festival in town on the same day called Rock n’Vintage Roll Festival which celebrated vintage cars and items and there was even a best dressed prize. So there were loads of women dressed in 1950’s/Rockabilly style.
