Would appreciate any ideas on how to tackle this - old cottage, bedroom ceilings have noticable 'fault lines' showing through the wallpaper (yes, woodchip, on the ceiling) where the plasterboard sheets meet. All seems sound, but the lines look terrible. The rest looks fine, so wondering how to cover up these lines? Thinking of sticking on wooden battens, painting over, making it look panelled? Anyone had similar or had any ideas? Stripping the woodchip is not an option, I'm sure it would end up with plaster coming off, and the cost and mess of that is not something I can deal with at the moment.
