My darling nephew has just pulled our blind off the wall. It's the second time he's done this, so there are lots of holes in plasterboard from when I bodged re-erecting the blind when he broke it off the wall the first time. It is a plasterboard wall which is shallow (not much depth before you hit what I assume to be the lintel).
Due to the fact that there are already holes where I need to re-erect fixings, how can I get blind back up? Would it help yo put a wooden batten up to put fixings on?
Hollow plasterboard walls are very tricky! Any advice greatly appreciated.
