Ideas Needed

Help if you can! I have a huge window in my new living room. I thought I had the curtains all planned out but I have run into problems. Problem #1: most curtains come 84" long. The next length available (usually not in stores but in catalogs) is 95'. Eighty-four inches hits the window where I have drawn the hot green line (this picture by the way was when we were getting ready to paint and had the windows all covered for the sprayer.)

I have already purchased a double rod because I love sheers but I also wanted something heavier so one cannot see in at night. So I was going to put the sheers on the inside rod and something else on the outside rod. I can solve the problem of height with the sheers using rings, like you see in the post below. No problem.

Problem #2: The window is 8 feet wide. The widest sheers I have found are 60". So I have 96" window and 120" of curtain. Yes, it will cover it, but does not give much fullness. I did notice that JCPenney has pinch pleat drapes that come much wider and you can put them up with rings. But I wonder if that will look dumb???

Problem #3: The outside curtain. I have problem #1 and problem #2 above with the outside curtain. I don't know how it would look to have both curtains on rings. I kind of wanted the variety of having the sheers on rings and the outside one hanging from the rod pocket. I do know that it would look absolutely retarded to have the outside curtain 3" off the ground. So even if I get that predicament figured out (buy the longer curtains and hem them--groan) there is still the width issue. How do you get them full enough without having a seam (I think that is going to be unavoidable)? Does anyone know any brighter ideas?
