I sketched this up for a friend long ago and shared it on sewforum and craftster. Little did I know that it would find it's way onto tons of sites, pinterest, blogs and all without any credits given! shame on me for not marking it with my information before sharing.
Anyway, it is a diagram of constructing booth walls from pvc piping to hang curtains on. I designed it for indoor shows when you want to separate your booth from the back of other booths, give you a nice neat look, and it's easy to set up, break down and transport.
Just some tips: I used 1" pvc, but I would recommend 1.5" so it is a bit sturdier. I hung my curtains on the top rods before I constructed it through the casings, but you can use shower hooks and buttonholes if you want to hang them after the booth is set up. Or you can use drapery rings with those little hooks or clips on them. I just like the way my drapes hang with casings. you can change the booth depth by shortening the top and bottom pvc pipes, or leave the front section off for a 5'depth. The back width of the booth can be changed in the same manner. Any questions? feel free to ask. I don't always get into the forums here, so feel free to contact me through my shop.
Here's the diagram, now with my credits on it. Feel free to share with fellow crafters!

I'll try and find a photo of the booth with the curtains on it for you.
