Hi, I think it would look nice to blend the fabric coloring to the wall color & add a nice trim. [there are so many great more casual trims; even geometrics] This will just add visual interest with just having softness/ texture to your kitchen. I would also elongate the window by using a roman shade/ or faux roman shade- mounting it almost to the ceiling. See picture from my Instagram (agherron) below. Have fun finishing your project!
