How about Velcro!!!
If you have time and funds, build folding frames out of 1x2 and tack or drape the fabric on the frames. I have seen these used in a small theatre group and they work nicely and store easily. The cloth was tacked to the top so it draped and flowed. The panels were light, tho somewhat large for storage if you don't have much space. Basically, they are empty screens. And you can use them over with different fabric if you need them again.
It is a rod. There are rods with internal spring with rubber ends to prevent damage. Found in any store that carries curtain and/ or shower rods.
