That looks like a valance on a decorative rod. It looks stationary. There may be something like that out there, but I have not seen it. Blinds that roll need some type of hardware to make them work. There are blinds that roll up using strings, but I think they always have a curve at the bottom. Here is a link that might be useful: Blinds roll up with strings

I just happened to see this and remembered your post. Don't know if it will work for you...scroll down to flexible rod. Here is a link that might be useful: flexible rod

The dining room: Love the wall color, and I know you donâÂÂt want to hear this, but I love the color of the furniture. I think you could have an elegant, almost Gustavian look going on in there. I would change out the hardware to something in a brushed nickel finish. Love the chandy. I would want drapery panels in here, and would treat each window separately. Something like this might work, and would pair the rich wall color with the lighter finished furniture: audrey drape Then something simple for the chair seats: grace teal Try the trio of vases you have on the window seat in the FR as a centerpiece grouping on the DR table if you go with these fabrics. If you donâÂÂt want to use the cabinets for showing dishes, you could get some of the window wallpaper in a simple frost and cover the glass. etched glass wallpaper for windows Gathered sheer fabric is an alternative, but I am not sure that works with the style of the furniture. Or, take the cabinet out completely and use it in the sitting room as a bookcase. Replace it in the DR with another side piece, perhaps a solid wood piece in the finish color of the tabletop. I will say, tho, that I like the cabinet in the DR in part because it balances the height of the windows. For the sitting room, it is hard to say because we donâÂÂt know what the furniture or flooring will be like. But I would again think about panels, perhaps something in a textured linen or chenille, for a more casual and cozy feel. For the FR, I would like to see woven wood blinds or regular wood blinds to bring the floor color up to the window level. You could add fabric valances above the windows for some softness and color, and do matching or coordinating cushions on the window seats, and pillows for the sectional. You have a lovely home - how fun to have lots of great spaces to decorate.

If you don't need the drapery panel to close all the way, you could use 2 short rods, one on either side, and hang the panels that way. Or, if you need the drapery to close all the way, you would need a an H-rail rod, pictured below.Hang the rod at the crown, with 2 "center" supports, one on either side of the arched window and the ends. The type of bracket shown allows the drapery panels to move freely with no obstructions.
