Hi chaps and chapesses

The problem is in 4mm

I'm building a 3 road engine shed to replace an earlier effort that I messed up
I'm doing one to a Midland design style so it has a pitched roof with the top half being Glazed

Walls OK -- brickwork no problem

Broken Glass - HOW????????????????


I will be using a polycarbonate film roughed up in areas to take thin paint to look dirty but How do I make convincing broken edges in the Roof light

I have got the walls and side windows in before I realised I needed some breakages as well as dirt - the dirts easy


Over to you lot and your expertese
