When I wanted to hang a vintage fabric panel in the corner of my family room, I used hollow copper tubing that can be found in the plumbing department of Home Depot or other big box store. You will also need a bending kit which shoud be around ten dollars. I think I paid four dollars for a length of tubing. I left the ends open, because I liked the look, but you could use wood plugs or some sort of finial if you want a more finished look.
I have had this up for a few years now and it still looks good!
