Could use a little sprucing up. If you don't have any art in mind I'd just go to HomeGoods or something to see if anything pops out at you. Also, overstock.com has sooooooo many rugs and runners!

Cynthia- would It be too much if I hung picture frames on both walls?

I wouldn't overrun the hallway and only do the triptych of frames and a runner.

I think both sides might be too much; I like where you've placed the 3 together.

It's impossible to know what colors would work since we don't know what you like or what colors are in the rest of your home. I'd probably find art I love, then find a rug that complements it. If you do that, you can post back here for help finding the perfect runner. You can do it the other way around (rug first), but there are a gazillion rug choices. It may be harder to find just the right art.

I agree to just that wall. Doing a gallery wall of family photos might be fun there.

For lots of ideas, search long narrow hallways on Pinterest.
