A panel on window panels

Question: When you have 2 narrow windows very close to each other, do you treat them as one or do two sets of curtains on each?
Curious about putting white shears across both sets then a panel on each far side. Would that be weird or do people do that? Or maybe just white or neutral curtains all the way across. Hmm!

We don’t move until mid-April, but these are the things I wonder about at night. I’m a nester. Just excited about the new place!
