OK, like the title says, here's 5 creative ways to decorate your Murphy bed.  Read and enjoy!

1. Hang curtains!  Curtains are a great way to add a splash of color and texture to a room, and they’re easy enough to change with the seasons, trends and you! 
2. Put up decals!  Some of my favorite wall-cling sites are VinylWallArt.com and DaliDecals.com.
3. Use wallpager!  The space behind a Murphy bed is small, which makes it the perfect place to use that fancy and "way too expensive but you love it oh so much you must have it somehow and someway" wallpaper. Ferm Living Shop not only offers sensational wallpapers but they have their own matching pillows.
4. Add lights!  Not only is it quite delicious but adding light to the space behind the bed and in the surrounding cabinetry will create the illusion of a larger space.
5. Put up a canopy!  Overstock.com is a wonderful source for inexpensive circular canopies or if you’re a Do-It-Yourselfer, check out this great tutorial on HowToDoThings.com.

Here's an example of what a decal can do with the space behind your Murphy bed along with a cool shot of a mirrored headboard!
