ABSTRACT
Fixing at this stage also effectively reduces the disproportionately thick-edge appearance of the wall string and, if worked out, perhaps by packing the wall string when fixing, it can be gauged so that the remaining thickness of wall string equals the thickness of the skirting board that will eventually abut its ends at the top and bottom of the staircase. This is an important point on good quality work, because abutting skirting boards ought to be flush with the string-face.
