Matching up the pattern sacrificed the lines of the pattern being level across the wall. 
Lovely design and I’m sure it’s hard to tell from the photo I uploaded but when you’re standing in front of it, the design gradually sags from level at the first one or two strips to lower.
 As a designer/perfectionist, this is bothersome. I do hope it will be less noticeable once the room is staged as I do love the look as an accent wall.
 The design also did not match up perfectly from sheet to sheet, it was impossible as you begin by lining it up, by the bottom for some reason the lines were not aligning exact. 
Peel and stick is not as easy as it seems in my opinion, but with patience and perseverance, it can be done less messily than the traditional way. 
It is forgiving as you can peel away the paper after you’ve started to make adjustments.
