Bought the rings to match the rod, used on sheers, looks gorgeous! Easy to use, you can make the pleat big or small, just attach the rings wherever you want. Makes it easier to open and close curtains. They're very high quality for the cheap price, too. I used five rings per panel, they come in packs of ten, so you'll need one pack for each window, assuming you're using two panels. Really gave it a nice look for a change of pace. I like changing curtains for the seasons, these rings add another look, too.
