Some Non-Woven Wallpapers Crease Easily

This is the bottom of the strip , where it meets the wainscoting . It needs to be pushed into the right-angle between the wall and the molding, so the excess can be trimmed off.
No matter how gently I push, or what tool I use, or how carefully I approach this, some papers buckle and fold and crease as they are bent backwards into the corner .

The wallpapers that do this are typically the thicker and ” puffy ” non-woven / paste the wall materials. It happens in just about every right-angle corner. Luckily these areas are usually not in the line of sight, so not very noticeable.
Note that many non-wovens are thinner and more flexible , and do not present this behavior.
