I like the idea of taping off a head board design and painting on wall.maybe the guest room? I love black walls! I have black walls in my dining room, I can't wait to try one black accent wall in my bedroom.
Display bits of fabric that you like instead of keeping it in a box. Fabric is art in itself. You can find embroidery hoops all the time at garage sales and thrift shops! Maybe even paint the hoops to give a little color to the fabric hoop wall!
I have been in love with these from Crate & Barrel since I saw them two and a half years ago! This gal created her own with watercolor paper, watercolor paint, stencils, and frames from Target! I could even change the colors to MY color scheme!
