We bought the largest size to cover an office wall and it looks great. We did not use the hardware that came with it, and instead just used command strips, as it is light enough to do so. 

The photos are not quite accurate on the color. The blue seems about the same, but the "parchment" color is definitely more yellow/tan in person than the lighter grayish color in the photo. I don't mind the color difference, but if you are looking for a cooler tone, this is definitely warm in tone.
