I want to decorate my very tatty hall. It's a Victorian house with stairs, a half-landing then more stairs to the 1st floor, so has quite a high stairwell. I am stumped as to how I can reach the top of the walls to strip wallpaper etc. I have a long ladder but am wondering how I'll use it on corners. I can't really afford to hire a professional. Has anyone done a similar hall themselves? Thanks.
