It has so many layers of paper and paint that that you can see all the seams and borders - and it has bugged me for years. This is the last time I will be able to tackle a big room like this - strip everything off and prep the walls properly - and it will probably take me 18 months. Aiming to get this one wall done before Christmas this year - and everything else done for Christmas next year. Just going to plod along slowly doing half an hour as a time - and this is the first half hour. That wallpapers stripper is wonderful!
