second suggestion, if you use drapery hooks onto rings the drapes are easier to open and close, and actually push back further.

3rd suggestion: i have lightweight "heavy sheer" panels inside mounted below the transom in my windows such as yours hemmed to window sill height, to open and close during the day for light control and all through the summer thats all i use. my floor to ceiling sink drapes mounted above the transom i only close at night in the winter.

Mounted in the wrong place, looks like ready made panels that are way too long, light gapping in the sides....? they need tiebacks so they don't just hang rumpled.

Your window is beautiful! What is your functional requirement for a window covering here? Decoration, privacy, sun control,...?

The windows are beautiful, and I love the chandelier! I would definitely suggest moving the drapery rod up to above the smaller windows. I would also suggest hemming the panels or getting custom panels so that the drapes hit the ground more like this

I believe there are custom treatments for arched windows, as well as curved rods that accomodate an arch.

The rod is too short, you want your panels to stack outside the window frame not in the window if you can help it.

If privacy is not an issue, I would leave these windows undraped. The trim is made to be admired, not covered up. If you must have drapes, you need to extend rod to eliminate the gaps on the edges and raise them so the transom trim is hidden behind them. Hem them to barely kiss the floor. I would remove the struggling plants to a sunnier spot and center the rug with the window.

I am in agreement that the treatments need to be hemmed.

Curtains should be above the transom, have more body to the fabric and less puddle on the floor.

Hanging curtains below the transom is perfectly fine - it allows in light. I do think the "puddle" style is not used any longer (and especially if you might choose to operate your drapes each day can be cumbersome).
I agree with one of the poster's comments that the window is lovely and needs no window treatment unless privacy is an issue.

Beautiful windows! If you don't need the draperies for privacy, take them down and enjoy all the added natural light in your room.
