I have so many mirrors & pictures displayed against the wall, on the floor
because I am too scared to put them up.
I would like to put some above the radiators around the house, but I am aware there will be pipes behind there. I believe they will be plastic pipes, so I can't use a detector?
It's plasterboard I presume, as it's a new build and the walls sound as hollow as a cardboard box when I wallop knock them.
I have no drill, just loads of the pictured fixings.
Should I just hit & hope?
