You have a couple of choices. If you want to convert to grommets, you could look into the kit, though I have never done this, and suspect it might be a bit pricey. You CAN buy a header stiffener in the drapery section of Joann's or a similar store, and I would think you would definately want to use it. A couple of other options: You could buy clip on rings. There is a small clip on the bottom of the ring, which clips to the top of the panel. Then the ring goes over the rod. Probably want to clip a ring every 4 inches or so along the top of each panel. If you want to hang them on rings,but don't want the look of the clips, here is an easy solution. Go to Joann's or some place similar and buy rings which have little metal eyelet-screws at the bottom of them. Unscrew each little eyelet-screw from the ring, and you will stitch it onto the back of the drapery, by hand, probably every four inches or so. You will stitch around the eyelet part. The stem end will be sticking straight up. Where the stem meets the eyelet -that part should be right a the top border of the panel. When you have stitched them all on, simply screw the rings on to all the eyelets and then hang the rings from the rod.

I had all kinds of ideas about how I thought it should be (I don't know why because I never have had grommet curtains) but decided to google it. I was sure it would look odd and maybe depend on the wall color and/or the curtain color, etc. But I turned up this page on sunbrella with all sorts of combos and they all look fine! I think the light grommets blend nicely with the fabrics. many more colors: http://dfohome.com/outdoor-curtains/sunbrella

If you are keeping the black framed art, I'd go with black rod, and you can lighten it up by purchasing a dark rod with the cracked glass looking crystal bulb at the end of the rod. Just a thought. Sometimes black can really anchor some things well.

My comment on this is that whether the curtains or draperies are ever closed or not, they should look like they could be closed, because that's what they are normally for when they are hung at a window. This sort of treatment says "I am a non functional piece of cloth hung on the wall". That's okay, I guess but plain tab top isn't even that decorative. In my opinion the above would look perfectly fine if the rod went all the way across.
