Deciding on Decorative Paper

I've been wanting to line the back of the entertainment center in our family room with some sort of patterned paper, fabric or wallpaper for awhile now. Besides bringing in some more print to the space and adding a bit of whimsy, I think it will lighten up the whole thing and help the huge expanse of black feel more integrated into the room.

{this is one of those gigantic entertainment centers with the tv in the middle, cabinets below and a bookcase on either side...sorry...don't mind the holiday evergreen garland}

I love Paper Source. And they have some really beautiful decorative papers out now. Hand-crafted in Japan and India, using fibers grown in Nepal, batiked, silk-screened, inspired by textile designs (or even their own in-house stuff)...they're very global with lovely small and large scale patterns, even metallics. I'd like to use cool tones - greens, blues and/or greys - and I think all of these are contenders. (I plan on mounting the paper onto foam core, cutting it to the size of each opening and then sort of wedging it into place so as not to harm the actual bookcase. Or I guess I could mount it on poster board and glue dot it to the entertainment center? Anyone done anything like this before?)

2. {Batik Mums on Turquoise}

3. {Chartreuse Birds on Pool}

4. {Pool Daisy}

5. {Flora and Fauna Pinwheels}

6. {Flurry Moss on Pool}

7. {Yuzen Pool Gold Waves}

8. {Yuzen Pale Aqua Gold Waves}

9. {Gold Leaves on Turquoise}

10. {Yuzen Cherry Blossom Clusters on Pool}

So pretty! I think I'm going to have a tough time deciding. It's probably worth ordering one sheet of each of the potential winners and seeing how they look for real in the space, huh? Which ones do you like best?
