Do you have hallway art or hallway photos?
I think it makes a long (dark, in my case) hallway more interesting and pretty. I've also added mirrors to reflect some light. You could use all the same color frames or do a mixture.
I started with the big mirror in the center and then worked out from there. You could fill the whole wall if you wanted ~ a gallery of your favorite photos and artwork.
Well, today I'll be spending more time outside because the weather is cooler, finally. After weeks of 100 degree days we got a break. This morning when I was sitting on the back porch having coffee I was actually chilly. Otis and Riley and I had a long walk to the park, and now it's out to the garden to dig in some dirt.
Enjoy your day!
