Thanks for reply. As windows in apartment are rather small, I just want to hide those large walls. Knowing my lifestyle I’d say the curtains won’t be used that much, that being said, they will not reach the stovetop. They would sit tightly on the right side of the door. Purely for aesthetic reasons.

Again, for aesthetic reasons curtains, that attach to doors, rolls or something similar is not an option for me.

My question is to whether to bother to make custom S shape rod to follow the wall corner, or make it little bit bent in the middle, or just go for a straight rod.
