Suggestions?

Obviously, there's a space that needs to be filled here. I'm thinking probably not natural wood because of the wood counters and orange walls (a bit too much, I think). I had thoughts of making a thin frame out of various shades of green glass subway tile, but haven't found the right size or colors to make it look how I want it. Also had thought about a twig frame painted white, but currently have no twigs. Something modern and simple would be nice. I'm looking and coming up empty. Any suggestions??

Completed project

Ok, false advertising. The only project we've yet to complete is buying a new dog bed (because it was a one-step project). Our other project is stalled in step 4 or 7 or 28, I'm not sure. The sink, countertop, and faucet are in. The paneling behind the toilet needs more paint, the exhaust fan is missing, and despite searching the greater metropolitan area for the right mirror and considering multiple do-it-myself mirror frame projects, the space above the sink is mirror-free with no prospects. I'll try to get some photos of all in process so maybe I can get some mirror suggestions. In the meantime, at least Ruby is enjoying the benefits of one complete project.

Latest project

Here's a mock-up of the most important part of our latest project. More to follow as it all comes together...
