Joyce, I had been thinking something similar to that too or some swirls to echo the borders. It's possible that my main objection was to the thread color choice.
Sewnoma! You have great taste
The only reason I got to this one is because I was waiting on a quilt top that was supposed to arrive but ended up being late. I didn't want to start something big so I took care of a couple of smaller projects and that was one of them.
ghostrider - more points that I hadn't thought of. Thank you so much for that. The curtain can only be hung in one direction so for now until I finish the 2 quilts waiting for me as of tonight, I will just rotate it 180 degrees if needed and add some more quilting to it once I'm finished. At least by then I will have a quilting plan for sure!
