also have uploaded a photo of our piano and mirror which I love. and I photo of our dining room light which I would also like to keep there.

I assume the windows abut in the corner? This would make it tricky to have romans as they would probably clash when both drawn up. Curtains drawing away from the corners add softness to a dining area, but make them floor length as short curtains look a bit half mast. It is also a good idea to have them wider than the windows to allow more light in when opened and fitted from above the window to elongate the window.

Anything can be done, it's just a matter of cost. For a job that size, I would try a local makerspace if you have one of those in your city. Hopefully there will be an artisan of some kind who can help you with it. Otherwise, maybe call a hipstery reclaimed furniture store and see if they know of a small business or artist who can make something for you.

Personally I think the curtain colour is fine, but your header tape needs attention and for me I'd have them taken up so they hang to the floor rather than on the floor. If your hubby is handy maybe get him to make u a box over the curtain header & stain/paint it to match your furniture. Or put up a pole in matching wood.
