I picked out a vinyl saying to go above my bed when I made my mod leaf pillow shams, and I finally got it put up. I had my sister-in-law Jennie design and cut it for me. You can check out her shop here.
I also made this white-on-white "W" to go above my nightstand inspired by the canvases here, only mine is the $3 version. I figured my bedding was so bright and colorful that I needed some white on the walls. Master bedroom update...check!
