Take a look at these beautiful accent walls....
The living room in the first set of photos is from the home of Jesse of Good Girl Gone Glad. Jesse used a stencil she downloaded from Jones Design Company and painted on the pattern using a small craft paint brush and a high gloss paint one shade lighter than the main wall color.
The master bedroom in the second set of photos was designed by Rethink Design Studio. They created an accent wall in lieu of a headboard by designing a graphic template, repeating the design, printing it on a large scale printer, and tracing the outline with a gold metallic Sharpie marker.
The living room in the third set of photos is from the home of Maria of Layers of Meaning. Maria and her husband created the chevron wall using painter's tape and three coats of paint (main color was Sherwin Williams Amazing Gray and accent color was Glidden Smooth Stone).
