Obsessed. It was difficult but not impossible.  Lots of math and cuts to make sure that the pattern was consistent from side to side. I used a different method than the very minimal instructions stated. I took the width of the wall and halfed it. Then figured out how many strips would fit so I ended up having the same small width on either end and it looks very even and balanced. Pro tip - buy an extra roll even if the measurements say you dont need to. Example. I needed less than two rolls but bought three. Gave me factory edges for each strip especially on the ones that were far less than the 20.5 width of the roll. I do have a lot of left over. But Id rather have factory edges and leftover instead of not enough!
