The Seemingly Everpresent Accent Wall

Ah, accent walls: how I covet thee. I want a light, light green in my bedroom, and a chocolate-y brown in the living room. There are a few obstacles to the attainment of accent walls, however.

a) My landlord. I think he'd say yes, actually, but he scares me so I never talk to him. Yes, I am fearless indeed.

b) Sloth. I kinda don't feel like it. I'd have to, you know, move stuff. And tape things. And, well, paint. Ew.

c) Cliché. I am already afraid my apartment looks a little too Pottery Barn-y. If I add a brown wall, I'm only a step away from putting my books in the shelves backwards (you guys know what I mean, right? Why do they do that?????).

I think that in the end, the accent wall is not for me. But a girl can have her design dreams.

But seriously, why do they do that?
