It's such a fun pattern, but... the backing paper tears so easily, so as we're trying to get all those bits handled, the paper folds in on itself. It's also very stretchable paper, so as you try to untangle the mess, it is stretching and you no longer have a straight sheet.

I guess the good news is that it's such a wild pattern that you can't see every bubble increase. I've installed a lot of wallpaper, but I'm really struggling with this one. 

I would advise ordering quite a bit of overage and don't work in large lengths. I am overlapping seams, and they aren't visible.
