I had a room lined and painted a few years ago. The finish seemed fine although I had noticed a few cracks in the lining paper and minor lifting on a few edges. Just had a paint redecoration but now there a lots of visible edges. The decorator was great so I can't really fault him but now wondering what could remedy this. I have thought lifting the loose edges and pasting then sanding down lightly then another coat of the emulsion would help. I can't face stripping. Its not too bad but I don't like seeing these edges as other rooms are not like this. Any advice
