I got a pair of these panels for a 72" wide window. I got to get two more for it to look right, but these pieces are nice.
As far as the rod, I used a 1 3/8 wooden dowel rod, used a center support, and it's fine. I"ve seen reviews where folks had issues with the rod not holding and such, and then blaming the curtains or the seller. I guess they need to mark these curtains "Some Common Sense Required".
