If you make blocks, you can run them end to end and then add a top "border" that is wide enough to double over and double seem for a rod to go through. That's what I did in my dining room and everyone loves them. I also added a small "binding" all the way around to finish it off. I didn't add batting because of the bulk but just used a coordinating backing instead. Another small tip...All of my windows have the spring loaded rods (like showercurtain ones) that sit inside the casing. No nails needed! You can also use the clip type holders so you don't have to create a rod pocket if you are so inclined.
