How do you lot board round these i.ve not come across one yet where i can screw a board or double board so it looks square. One we did yesterday had been boarded and was a pain and bet skim was bout 10 mm at bead.
I find best way is to screw a board on to timbers then dot next board on pushing in to the groove and squaring to window with corner of plaster board
