Michele H. I bought a few gridwall every year, and worked my way up to the big shows! I use 3 6 foot tables, and 3 4 foot tables, but again, I bought a couple at a time! Now I can do a 15 x 8 foot booth with no problem, but I didn't have all of that overnight! Gradually work your way up to that, if you want to think about the bigger shows. It IS expensive, especially for indoors, where you need good lighting as well.
