To mark a new spot dead center in a Newt.mirror, cut a square piece of paper the same size as the mirror. Fold the paper twice and cut out a small piece, perhaps 5mm, in the corner that forms the centre of the paper. Place the paper over the mirror and, with a dark coloured marking pen, make a dot through the hole that you cut out. Perhaps 10 mm in size.
