This wallpaper was the inspiration for our redesign of our downstairs half-bath.  I decided to prepare the wall with primer and also add a little paste to fully secure it to the wall. I’ve worked with wallpaper many times over the years and this does not really smooth or go up like wallpaper.  I lost one roll to the paper crinkling which leaves permanent marks you can not smooth.  I love the look but I won’t buy peel and still again because it is temperamental.
