Sprucing up a Tiny Space

I've been going back and forth on my decision to wallpaper our downstairs powder room. After seeing these fun bathrooms in Lonny my mind was made up.  

Now I just have to decide which wallpaper I'm going to do.  Here are some I've been loving.  

All of these wallpapers are from Sherwin Williams or American Blinds  and are $30 or less a roll.
