    I want to make a flat roman shade with ribs on the back. Do you have any suggestions for this? I’m still not understanding how to convert the top to make a top down shade. Please help! Thank you!

      Hi Pat,
      It MIGHT be that you have a pop-up blocker on your browser. Try disabling that. Also, sometimes the window is already open. Go to the “Window” menu in your browser and see if it’s there.
      Hope this helps
