I've read previous posts on this topic but am still not sure whether pasting PTW paper instead of the wall is a bad thing or a complete no-no. I had no choice with the paper (strong willed granddaughter!) but would much prefer to use the normal method which I am very happy with (and good at). One needs flexibility in the paper when doing behind/around an electric socket for example and it seems to me that PTW paper would not be so easy to use in that area. How does the technique of overlapping at a corner then cutting through both layers work with PTW. Basic question -if I paste the (PTW) paper, will I regret it and why? The fact that it is (allegedly) easier to use doesn't bother me at all. Gdad.
