I don't know your case, but I haven't seen a curtain that wasn't held with a curtain rod. It might be a match to your other curtains.
I have made shower curtain rods from PVC pipe, use schedule 40 (thick wall).
To obtain the correct shape I used a heat gun to bend a curve or corners. Then attached the rod with stainless steel screws. Standard shower curtain hangers and curtains could then be used.
