Much as I love the wallpaper I’m very disappointed to learn from my decorator that it’s well nigh impossible to ensure the seams don’t move apart a fraction on drying ! He ( an experienced professional decorator) states it’s a common feature with paste the wall, wall coverings,and there’s no way around it. Of note there were no seams evident at all when the paper was first hung.
Sure enough the seams have moved apart a very small distance, never happened to me before & I’ll be sure never to purchase a paste the wall paper again
