this is the 3rd time I'm put up removable wallpaper and this one was the hardest for me.  I think it wasn't quite as thick as the others but wasn't impossible by any means.  At first I was disappointed because there were so many bubbles and they just weren't coming out.  After 2 days, they were gone on their own!  I just did an accent wall in my guest bathroom and this wallpaper is MORE BEAUTIFUL in person.  I would highly recommend it.
