My mom is an amazing seamstress. While I was visiting her last week, she made my kitchen curtains for me. I helped out a little and took notes. The one above the bay window is one long continuous valance. We made them one and a quarter times the width of the window so it would have a little bit of gather but not too much. And I'm pretty amazed at how the red bouquets are perfectly spaced out over the width of the windows.
