Generally the rod extends beyond the outside of the window casing, and the stationary panels frame the window, just covering the frame. Thus there is wall behind the stationary panels, not window. So you are going to have roughly 70 inches of rod showing.

Yes, get four panels. And get a nice fat rod to put the panels on - at least a diameter of 1 3/8 inch.

thanks for the quick reply graywings

Luckily the rod I bought is long and fat enough...

Try Country Curtains on-line. I've bought most of my draperies there and am very satisfied with quality, price and service. They even send you small samples of the materials and colors you're interested in for the curtains. The look is not just country but can be very sophisticated; they've really expanded their line over the last few years.
