Panel style curtains - look ok on a plastic rail? - clothes hanging rail

Hello
I'm going to make curtains to cover the facades of some clothes in open shelves. The areas around the shoulder height and 40 "wide.

My plan is to make the plates in a light cream (I know, boring! But it is a very small room) and my question --

"The characters look strange, hangs on a rail made of plastic, as it is flat, without curtains, which are typically occurs in the rule?

I like a wooden stick, but must be a very modest version, or size of your thumb, not the usual size. I do not think that they do not (come near where I live anyway).
