Not everything from the 70s in our house was awful. There are a couple light fixtures in the hallway that are actually pretty cool. As you can see above, they are mostly clear with a crackled glass look. The only problem was the ugly CFLs inside. We lived with the lights like this for far too long.
We have a very complicated relationship with the vertical blinds in our dining room. We recognize that vertical blinds are generally terrible, but we didn't have a better solution for blocking the glaring sun in the morning, so we kept them. Deep down we knew we should get a valance to cover the ugly rail for the blinds, but we could never decide exactly what it should be like, so we did nothing. That all changed when we found a giant valance sitting on the curb down the street from our house.
