We prefer blinds. love the look of curtains but they don't offer the versatility of blinds, in my opinion. Blinds give ventilation and privacy. Our original (2016) Casita blinds were a low-grade aluminum that were easily bent and quickly began to pit and tarnish. After a few years we ordered new faux wood blinds from an outfit called Steve's Blinds and wallpaper, believe they're in Wisconsin. I think it was less than $150 for all windows
in total. 1" white louvers and no rust or pitting, quite nice and sized per window. We tried the local Lowes/Home Depot route but found that sizing to length was really difficult and not worth the effort. To each their own though, some like curtains and valences and the comfy look but we like a more minimalist look. Nothing wrong with either.
