How large is your booth space? Is it outdoors?
This is how I set up my booth last:

My biggest struggle is displaying full aprons well. They tend to lose their shape and get lost on a rack. I tried hanging a few from my tent, which got people's attentions, but the wind picked up and next thing I knew, my aprons were waving like flags.
I'm considering a grid wall but I haven't considered it hard enough to actually purchase one. Let us know what you come up with and how it works out for you! Good luck!
