I just bought some drapes that are part silk from Penney's. They look just like the Dupioni's sold at Pottery Barn but are priced much better. Lined and everything. Penney's also had the rods you described as well, you may want to see if they have what you're looking for.

You can also get those kind of rods at Lowe's or Home Depot. It's called a closet rod there. Much less expensive than buy an already painted rod. Lowe's carries the unfinished brackets and finials too. I've not seen the large rings unfinished though.
Here is a close up of the rod, finial and rings I found the sew on rings at Sears years ago on clearance. Not sure they have them now.

Sorry they are small and one is blurry. I took them with my old 2mega pixel cell phone camera.

Personally, I found the silk curtains at JC Pennys to be skimpy on fullness. I prefer the ones at Restoration Hardware or Pottery Barn which are lined. If you look at their websites, you may find some inpsiration there.

As for curtain rods and rings, I've found good selection and value at JC Pennies, Lowes, and Bed Bath & Beyond.

Since you want to close them for privacy, have you considered a decorative traverse rod? You can still use rings with them. I think it will give you a nice look and the drapes will hang better since you will be pulling on them daily. There are many places that you can find them, just do a search. I really think that is your best bet. Good luck!

I just bought wood rods from Lowe's. I love that I can have them be 8' (+ a little extra that we added) and they are sturdy enough to not need a center support. This might not be important to you, but I have woven bamboo shades under mine, and I didn't want to have to support the pole in the center.

They were a very good price too. I think the 8' pole was only $24, and the 6' pole was $19. They sell the rings, finials, tie backs also.

I just wanted to say inspect your wood rod well because all the ones I saw at Lowes weren't straight and it would've been noticeable when up. I really wanted the 3" twisted rod but am glad I passed.

I know this isn't what you want but I ended up buying an adjustable one and had to use a dowel rod in the middle to keep it straight.

Valinsv, I'm not usually a big fan of Penney's and am sure some of their curtains are as you say...skimpy, however, I bought a Dupionis panel from Pottery Barn (89.99 per panel) as well as a panel from JC Penney (29.99) to compare and truth be told, they're almost identical. They're BOTH lined and have similar weight & color. I love Pottery Barn and the drapes I bought are to match a new duvet cover I got from there. However, to me, any slight difference in the draperies between these two stores (or even RH who's pricing IMHO is ridiculous) just doesn't justify the 60 dollar price difference.

Justgottobeme - Funny you should mention the drapery rods at Lowes. I found one there I loved and it was on clearance. I got the drapery panels I mentioned before, the 1 inch decorative rod as well as 3 boxes of hoops & clips for less than what 1 panel at Pottery Barn would have cost us yet it has the same look.

I bought the Supreme panels at JCP (like them a lot!) and wood pole & rings from Lowes to use in my LR. I wanted to be able to close the drapes easily when I was watching TV because the TV is directly across the room. What a pain! The rings do not slide across the pole easily, so I have to climb up on the ottoman and push on the rings. So, my plan is to leave the drapes stationary and figure out how to get some blackout fabric behind them that I can slide in place when watching TV.

I would consider either the traverse rod or using a non-wood pole if you plan on using them every day, Or I wonder if you can wax the wood pole to make them slide better? Mine's fluted, so I won't try that.
