there was some confusion , based upon the photo, as to what kind of curtain rings should be used. I inquired of customer service and they asked the manufacturer and responded it was the curtain rings with the clips. Although I did not understand what it meant when placing the order, the item specifications clearly state 
":Header Included - Header Type: Rod pocket" which means the rod goes directly through the pockets on the top of the curtain... If there is a way to use curtain rings with these, I am not aware of it. I will do a bit more research. I ordered two curtains, the curtain itself is a nice fabric with blackout backing and I am very happy with the look of them. The color "Ice" works well with my decor, it is a bright white with a slight bluish cast.
