I wanted to do this a few months ago but I was still pregnant and well lazy and wasn't about to start a big project like this until after I had the baby. I found a free stencil online and printed it off. I take absolutely no credit for the creation of this idea. And her implementation is way better then mine! Eventually, I want to paint the stencil on the wall the TV is on:
I still enjoy the stripe but a modern patten would be even more enjoyable
But that wall seemed like too big of a commitment for a something I wasn't sure I would like. Solution? The entryway. It's small and already painted aqua so I could paint the stencil in gray. Genius! Disclaimer: The entryway is small. The aqua photographs REALLY aqua. It's not that bright in real life. And, don't look too close because the patten gets a little wonky in places but the overall effect is great.
During. I started tracing the stencil with a pencil and then switched to a chalk marker because I could wash it off after the paint dried.
I know I didn't go into detail with instructions. If you want them go see the pro do it here. The plan is to finish the entryway (with a steadier hand), finish the TV wall, and then some sort of backsplash pattern.
