You need to post some pictures

We have three large windows and a patio door on our lower level. I feel like doing curtains on all four would be obnoxious. Am I right?

Do you need the blinds for privacy/light control? If not I would either remove them or raise them completely when not needed. I much prefer curtains over blinds/shades. You can extend the rod past the windows and use panels that can be closed if necessary ( be sure to use enough panels to be full when closed).

We do need them for privacy and light control. Lots of sun and lower level. We plan to update the blinds to Bali brand. I always use extra panels and extend my rods. next to decide what type of curtain design to use with sea salt? Something to tone down the honey oak? Linen, gray, design or no design.

I would use the same style as your pretty blue curtains but in an off white for the other room. The curtains create a beautiful, warm, finished look.
