Hey guys... Had to get a traverse (corded) double rod for a large bay window situation. The rest of the room is modern/contemporary styled, so I do NOT want pinch pleats. Trying to find other options for these is nearly impossible online. What other types of curtains besides pinch-pleat can be used on these types of rods? Or should I say, which other types of curtains are compatible with drapery pins that wont droop or look terrible? I found this picture online and I'd like to know how they did this. Any insight? It's definitely on traverse rods but it doesn't look like it at all... What's going on here?

Just installed new Bali (Springs Window Fashions) adjustable 1-way traverse rod over a sliding patio door. Excellent online reviews, everybody says these are heavy-duty, work smoothly, etc. The rod will fit spans from 84-156 inches approx; we need a 130 inch span so there is about 2 feet of "overlap" where the smaller, adjustable end of the rod sits inside the larger, fixed end. That's where the trouble lies. The carrier moves smoothly at either end of the span, but when it hits that middle "overlap" section it binds up like crazy -- can't move it by pulling on the cord, have to push/pull it past that area by hand. We've checked that the cords are not twisted, and the new knot (tied when cord length was adjusted for the 130 inch span) isn't hitting anything along the way. We've verified that the rod is mounted straight and level. It's definitely the overlap area causing the problem -- when we pull the adjustable end out farther and change the length of the overlap, the binding issue changes accordingly. I've emailed the company and messaged them on Facebook but wondering if anybody here has suggestions.
