Truly Trellis

My cousin has this new rug in her living room. The simple trellis pattern and color give the room a pop, yet it doesn't take over the room.

It looked great and felt great and she said she got a great deal on it through Rugs USA. I found the same rug in a bolder color here:

BTW, how great is this nursery?!? I'm thinking this rug in a bold pink would look awesome in Ana's room.

Or maybe take the pattern to the walls? As I was searching for a rug online I came across this pic:

How cool is that dark hallway?!

I must say though, the thought of stenciling kind of makes me want to hit myself over the head. It just looks so time consuming. Do you have any experience using stencils? What did you think?
