So I picked a small, one weekend, local faire. After exhaustive reading and re-reading of the rules, year one I went with a 'tarted up' easy up. Basically all of the metal has to be covered, and the canopy has to be made from fabric, not nylon. I made a canvas cover for the top, which didn't fit quite right, but it wasn't bad either. Then my genius idea: all the metal bits would be covered with fabric covered foam. I would just glue it together. It worked great, but not for the reasons you might think. You see, my canopy was a little on the short side. And when that canvas got warm, it sagged like an elephant skin. So, my tent started to shrink inwards. And all of the lovely tall men and women in their tall hats had to awkwardly crouch to enter my humble hat shop. And when they tried to make their escape, they hit their heads on the sidewall of the easy up. Good thing it was well padded, because it was a bit like watching birds run into your window. You wave you arms and say "look out!" then, BAM and watch with guilt and horror as your prospective clients wave off your apologies and try to reorient themselves.
So I saved my pennies and bought a 10 x 10 center pole marquise tent. I have to say, it is probably the most beautiful tent I have ever seen. It even smelled good coming out of the box. Wow. And the side walls are 7 feet tall, no more hat strikes. Now, it takes real ropes and poles to hold it up, and I am really really glad I practiced putting it up in my backyard before the event.
