I decided to go play a little and just stick it together so I could show you what I am trying to do. While doing so I realized I needed to cut my dowel rod off a whole bunch because it is wayyyyyy too long. So good thing I wanted to show pics.
One of the supports doesn’t have the holes cut out in it yet. But you get the idea. I will have this dowel rod and a smaller one. The larger one for the curtains and the smaller one the sheers. Or in the bedroom it will be the long valance and then I might do sheers with that, not sure yet.
