This house, built in 1963, has paneled walls. The previous owner was a professional painter and he mudded and painted them to look smooth. The paneling is still there but it looks like drywall now.
And in most rooms, the ceilings are the 12" acoustic ceiling tiles. I do not plan to remove them. They are in good condition, most have been painted (white, of course). Dated? Yes, but that's fine with me.
And the main bathroom is pink! It's like stepping back in time. In all of this remodel/reno, I am intentionally trying to keep the 1960's character.
And yes, blinds! When I first moved in, early summer, I removed the mini blinds and tossed them. Hung curtains. It wasn't until winter that I realized that the heat from the baseboard heaters was just going up behind the curtains. Now I know why they had the blinds; with the way the windows are installed, the mini blinds or those double layered pleated shades ($$$), inside mount, are the only choice, lol. One room does have the pleated shades. If $$$ doesn't run out by the time I get to windows, I will install that. Much nicer.
