In my 19, I use a cheap curtain wire kit I purchased on ebay.
I think it's a good solution if want to put the curtain away each day.
Very fast to put-up and take down. To take it down, we just unhook each end of the wire (the wire stays threaded through our curtain's grommets),then fold up the wire and curtain together and store in a cupboard. To install again in the evening, just unfold and hook the ends into the eye bolts.
Here's an instructional video.
