based on the drawing, the wall where the bed is. HOWEVER, you mentioned that this drawing is not a true depiction of the furniture you will use and the wallpaper. if that is the case, i think the wall paper can work on either wall, it all depends on how busy this wallpaper is and how "plain" the bed is. if you go with a busy wallpaper behind the bed, you may want to keep your bed and bedding on the minimal side so that there is a good visual balance to the overall composition. if you go with snazzier bedroom furniture, then a busy wallpaper may be a bit much and you may want to put it on the other wall or use a textural option to serve as the bed's background rather then another focal point.

Thanks It was through Houzz I was ordering it!!

No suggestions here apart from getting the wallpaper you want either shipped to you or searching around for it!

I am stripping 80s era wallpaper from our whole house in preparation for painting. Most of the house house been fine - the gib underneath has been in good condition. However in the 70s extension we have uncovered extensive areas of mould which is resistant to normal cleaning (warm soapy water). The gib itself is dry and we have cut a whole in the wall to check that the timbers and insulation appear to be dry as well. Does this gib need to be replaced or would a professional painter/decorator be able to clean it prior to skimming?
